Ans1: Growth is defined as the increase in size and mass of a particular organism over a period of time. It is measured in terms of biomass (mass of the organic material). An organism grows by mitosis. Growth stops after certain age of the organism. Growth is quantitative and measured by taking the measurement of height, weight, size and shape of body organs like brain, etc . Development is defined as the process of cells differentiation which helps in the development of the body. It adds complexities to the body (such as organ development). Development of the organism is a ...

Embryonic stem cell is a crucial factor in the developmental process of a multicellular organism. Embryonic stem cells (ESCs) are derived at early stages during development and eventually give rise to all type of tissues and organs in an animal. The ES cell lines have three properties consisting of self-renewal, primary chimera formation and pluripotency [1]. Pluripotency, a key feature of ESCs, refers to the capacity of a cell to differentiate into several different types of tissues [2]. An array of cellular factors play important role in maintaining pluripotency and determining cell fate in the developmental pathway. Negative effects on these factors may ...

Bioinformatics combines the subjects of biology, mathematics and computer science in to a single field of study. There are various tools available for the biomedical researchers so that they are able to find out the desired biochemical, genomic and medical information. Search programs, data base storage and software programs are some types of bioinformatics tools that help in the analysis of proteomic and genomic data. The web based tutorial of bioinformatics programs will be used in this study to analyze the most important enzyme of fertilization called phospholipase C-gamma. This tutorial will use the bioinformatics tools easily acquired from the ...
