Essays on Pairs

The chromosomal theory of inheritance is a theory that defines the role of the chromosomes in the execution of the process of Mendelian inheritance (Waddington, 2016). The theory makes a maximum application of the Mendelian laws of inheritance based on various observations. Some of the observations affiliate to the laws includes; the migration of the homologous pairs of chromosomes as discrete structures independent of the other pairs that exist in the same strand. In addition, the theory explains the random process of the pre-gamete occupation of each homologous pair of chromosomes (Waddington, 2016). The parent contributes half of the ...

Turner’s syndrome is a genetic disorder which mainly affects female growth and development. It is also termed as gonadal dysgenesis which occurs because of the absence of sex chromosome (X). The absence of the X chromosome causes abnormal development in human females. Instead of having a pair of 46 normal XX chromosomes, females with gonadal dysgenesis develop 45,X chromosomes (Castiglia, 1997). This odd combination of chromosomal pairing results in a conflicted sex of the person, where they are neither distinguished as male or female, due to the absence of the second X chromosome that would establish them ...

Introduction

Sickle Cell Anemia or Sickle Cell Disease is an inherited blood ailment. Those suffering from Sickle Cell Disease have abnormal S/ sickle hemoglobin in the red blood cells. Hemoglobin is the protein in the blood that aids in carrying oxygen throughout the body. The ailment takes its appellation from the shape of the red blood cells of a person affected by Sickle Cell Disease, which have the shape of a sickle. They are stiff and adhesive rather than a disk like normal cells. The misshapen cells tend to get trapped in the small blood vessels hindering the movement of ...

Introduction

Statistics is a branch of mathematics, aimed at collecting and analyzing data via different methods such as analysis of variance, kurtosis, skewness or regression analysis. Nowadays, statistics helps processing data with a help of creating various charts that in turn help visualizing complex data sets. There are two major types of statistics, descriptive statistics and inferential statistics. Descriptive and inferential statistics require proper hypothesis formation and thus proper selection of the statistical tests that in turn have to be analyzed and interpreted successfully.

Descriptive Statistics

Descriptive statistics implies application of various coefficients that simplify process of data processing and aggregation (Trochim, ...

Abstract

In the last century, the knowledge of molecular biology has increased, opening new opportunities for addressing different diseases that have been affecting all populations. Before, genome and proteomic studies were seen as complicated field due to inability to get significance understanding of disease components at the molecular level. However, with the expansion of molecular biology, different techniques and tools have been developed to aid diagnosis and treatment of diseases. In this study, these tools have been investigated to understand how the knowledge on molecular diagnosis helps in detection and treatment of diseases. This study focused on the application of ...

Hemophilia is an inherited disease that is likely to affect males. It is well-known throughout the history as the most dreadful sickness that prevented normal blood clotting. As a result, diseased people could bleed for hours or even days as they lack a necessary clotting component in their blood. The responsible gene is transmitted in the X chromosome, and this makes males more subjected to the disease. They inherit only one X chromosome, so if it contains mutated gene, it means that a person will surely have the disease. Females have a second X chromosome, and it is usually ...

Meaning in life (MIL) is a concept which is fundamental to numerous individuals as it is based on their values and it can be a source of motivation. According to Allan (2014), virtues and character strengths have been linked augmented levels of fulfillment and meaning in an individual’s life. In the book “Harry Potter and the Philosopher’s Stone” the concept of meaning in life is illustrated by a young orphan who pursues a great destiny. This story follows a young boy – Harry Potter who lost his parents at the age of one year after they were murder ...

The rediscovery of Mendel's works on heredity in 1900 became the foundation to investigate more on genetics. However, the acceleration of the study of genetics was slow, taking more than half a century later for Watson and Crick to crack the chemical basis of heredity. In fact, their proposal, the double helical structure of DNA, became the beginning of modern biology. Over the next 30 years, the advent of recombinant DNA technology allowed us to sequence specific DNA segments (Collins & McKusick, 2001). Note that mapping specific regions of a particular DNA offers explanations to many traits, including behaviors, disorders, ...

Biological factors that might account for Schizophrenia

Schizophrenia is ranked as one of the most severe mental ailments in different parts of the world. A person in 100 individuals develops the illness over a life span. It can develop any time but commonly shows up in the late teens to mid-20s. In addition, it is common in both males and females. Physicians are now embracing that, its results are dimensional across interlinked areas of signs; severity, functional or social disability, medication, employment and management factors. To describe and diagnose the philosophy of this disorder, numerous modern strategies have been suggested, since the prototype explanation by Kraepelin. ...

Trisomy

Chromosomes are marvelous things! They carry in their genes the entire genetic code required to build a human being. Comprised of nucleic acid (DNA) and proteins, twenty-three pairs of chromosomes located in the cell nucleus are needed for the normal development of a human embryo. However, sometimes things go wrong. This paper will discuss some of the consequences of faulty chromosome separation during fertilization, resulting in Trisomy. Trisomy is a chromosomal condition which occurs when three chromosomes, instead of the normal two are produced during cell division. This happens due to the failure of human chromosome pairs to separate ...

Introduction

The Myers-Briggs Type Indicator is one of several instruments that will investigate the personalities in people and assess them and give results that are easy to remember (in this case, the result is a four letter designation that lists preferences, or styles, in descending order). There are eight of these preferences, listed as pairs of opposites: Extroversion (E) or Introversion (I), Sensing (S) or Intuition (N), Thinking (T) or Feeling (F), and Judging (J) or Perceiving (P). Since one of each of contrasting tendencies will be listed, that results in 16 possibilities to describe the person's personality. It is ...

Lumbar spine – lower back. Lumbar spine is core support of the human body. It allows us to perform important functions like side bending, turning, rotation. One of main purposes of the spine is to maintain upright walking ("Lumbar Spine Anatomy: Overview, Gross Anatomy, Natural Variants"). 2. Ischium – sit bone. The main function of the sit bone reveals when we sit. ...

Integral to humans is a constant pursuit of distinction. This pursuit can assume positive, constructive or negative, damaging forms. On a positive side, hard work can be a springboard for distinction regardless of professional, social, economic and cultural barriers. On a negative side, distinction can be achieved at someone else's expense. In one most damaging form, distinction can be sought based on race. By emphasizing – mistakenly – one's superior race because of physical attributes, particularly skin color, distinction, if any, becomes damaging at multiple levels. This concept of (false) distinction informs Cohen's argument on race and culture. In his argument, ...

Method Description

A quasi-experimental research design will be employed. The nature of the treatment variable (gender) cannot be manipulated by the researcher. However, from the nature of the study, we can deduce a naturally occurring control group (adult-sibling pairs with different gender) and a treatment group (adult-sibling pairs with the same gender). Therefore, a non-equivalent posttest cross-sectional design will be used. A survey method will be implemented by the use of a questionnaire. Data will be collected using a questionnaire because it is time-saving as the data collection will go on concurrently. It is also cheaper than conducting interviews both in ...

Abstract

Transformation remains, and hugely significant tool in extending the borders of life sciences and medicine. It can be referred as fixing intracellular DNA into a bacteria or organism through the vector, thus transforming it. This paper uses plasmid pUC18, self-reproducing circular/spherical strands of genes that may be modified. After the bacteria absorb the vector, some proteins not usually synthesized will occur. In this study, a system has been developed to monitor the transmittance of different DNA (genes) from a genetically transformed strain of Saccharomyces cerevisiae to E. coli. This mechanism is centered on yeast strains that contain several integrated ...

DNA and its importance in our lives

Introduction Deoxyribonucleic acid (DNA) is a long linear polymer located in the nucleus of a cell. It is developed from nucleotides and shaped like a double helix. It is related to the transmission of hereditary information from one generation to the second generation. DNA contains the information for the development as well as reproduction of an organism, thereby leading to a normal life. In the year 1953, James Watson, a biologist, and Francis Crick, a physicist, discovered the structure of DNA in a laboratory in England (LEROY, 2003). The structure of DNA helped scientists to know the process ...

Which Features of turn taking occur most frequently in Brunei? In a face-to-face conversation between friends? Self-selection In Brunei, age is an important factor in any communication. Communication is in most cases formal. In the case of communication between friends, the oldest amongst the speakers usually has more power than the rest of the speakers. The youngest speaker is usually at a disadvantage than the rest of the speakers since he/she may rarely have any chance to talk and influence the others. Self-selection is common in the communication between friends. This occurs when two or more people begin speaking ...

The use of biometric evidence in executing criminal justice has gained reputation throughout the world as a result of rapid advancement in technology. In essence, biometric recognition entails the use of biometric equipment to recognize individuals through their biological characteristics (Sanders et al., 2010). Bio information of a person is captured and analyzed for use in identification. Some examples of bio information include fingerprint and signatures. A biometric evidence is the most popular and convincing method of confirming the identity of a person (Reedman, 2015). The criminal justice system uses different biometric characteristics to identify criminals depending on the ...

Young individuals experience a couple of changes that affect their behaviors and the way they interact with other people around them. During their adolescent period over 20% of young individuals experience depression disorders, which ends up influencing their mood, makes them pull away from joyful activities that individuals their age should engage in and have a negative attitude towards other people, events, and objects. According to Milne and Lancaster (2001), depression hails from various things such as failure of individuals to distinguish themselves from other people, distrustful relationships, and lack of proper parental care among others. This paper explains ...

Stanley Milgram who was a psychologist from Yale, conducted a well-known experiment about obedience which is relevant for human psychology. This happened in 1963 and the experiment was related to the fact that people were in conflict between their own conscience and obeying authority. Milgram was seeking for explanation of people who committed genocide because they were ordered to do so during WWII and he found out that obedience is a powerful impulse. Milgram was inclined to believe that people tend to obey the authority because it is a tactic for survival. “For many people, obedience is a deeply ...

I am writing as the head of the survey department. Our department involves working in the field to collect geodetic information. In many cases, different crews are situated in different location. But like any other technical job, there is a need to maintain constant communication among the crews. Sometimes an individual requires information from another person who is situated away from them; it takes us a lot of time to convey that information. Survey requires constant coordination among the crew. For instance, when doing leveling, the person who reads the stuff may be far away from the one who ...

There has been at least a dozen various human like species since the earliest homid species split from the ancestral line the humans shared with the apes. This was approximately 6 to 8 million years ago. Most of these homid human like creatures are just relatives to the human beings and are not their ancestors. Humans are more closely related to modern apes like gorillas and chimps more they are to the monkeys. It is believed that humankind shares a common ancestry line with the African apes, like chimps and gorillas. And it is believed that this common line of ancestry ...

Introduction

Biology is broad and therefore embraces various topics in life that concern living organisms. Micro biology for instance deals with the study of very small organisms that are able to reproduce and sustain their generations. This is where the study of prokaryotes comes into the scene. The contrasting organisms to prokaryotes are referred to as eukaryotes. Contrary to prokaryotes, eukaryotic organisms have complex cell structures. Biology tends to full describe the complete nature of these organisms, their feeding habits, how they reproduce and where they thrive best, that is, their habitats.

Prokaryotes are single celled organisms whose cells lack ...
