Essays on Histone

Cells are the building blocks of many structures in biology. In their most basic classification, there are prokaryote and eukaryote cells. These two cell types differ in their structure. Prokaryotes typically consist of ribosomes, a cell membrane, and nucleic material. On the other hand, eukaryotes contain membrane-bound organelles, such as Golgi apparatus, lysosomes, a nucleus, and endoplasmic reticulum. Both types of cells also have nucleic acid as a form of genetic material. The prokaryote has circular DNA which is not associated with histone proteins; whereas the eukaryote has linear DNA with histone proteins present to help organize and protect ...

{Author Name [first-name middle-name-initials last-name]} {Institution Affiliation [name of Author’s institute]} A cell is a form of the miniature factory that encloses a distinct chemical system that is involved in structural maintenance, homeostasis, energy generation and reproduction. Every organism is made of these structural living units. The cell divides and produces more cells and assists in the growth of the organism. There are two types of cells, eukaryotic and prokaryotic. Eukaryotic cells are characterised by a membrane-bound nucleus enclosing the genetic material. The Eukaryotic cells can be divided into three main parts, plasma membrane, cytoplasm, and nucleus (Cooper & ...

Epigenetics is the process of studying cellular and physiological phenotypic characters within the field of genetics. The study falls within the subject of genetics and the phenotypic differences which are affected by the peripheral environmental matters. These factors are notorious for switching genes on and off and also affect the way in which genes are read by the cells. Therefore, Epigenetics is the study that seeks to establish the dynamics alterations in the transcriptional potential of the cell. The alternations in this case, may or may not be heritable, even though it is controversial to use the term epigenetics ...

Introduction:

Chromosomes refer to a structure that consist genetic material and formed by DNA and protein. Chromosomes are coiled form of DNA that consist genes, nucleotides and regulatory components. Shape of chromosomes varies depending upon the species. In Prokaryotes, chromosomes are circular in shape and have one cell whereas in Eukaryotes, chromosomes are linear in shape. Bacteria’s falls in prokaryotes category hence have circular chromosomes. Virus is an agent responsible for causing deceases. Viral chromosomes consist of nucleic acid and protein. Nucleic acid could be either DNA or RNA; both do not exist together in viral chromosomes. Viral chromosomes can ...
