In this article we will discuss about the functional activities of gene in action. The functional activity of these genes which are needed in all cell types are known as house-keeping genes and those who are active or the activities of those genes are found only in some specialized cells are known as luxury genes. But from the point of [...]
In this article we will discuss about the Introduction and hypothesis of human gene evolution. Introduction to the Evolution of Human Gene: Some chromosomes appear to have been relatively protected from change during primate evolution, for example human chromosome 19 and X. By contrast other chromosomes have been prone to significant reorganization for example human chromosomes 1, 2, 3 and [...]
Two types of mutagens are considered here which are mostly affected the humans producing different mutations resulting in a number of abnormalities: 1. Radiation Exposure 2. Chemical Mutagenesis. Type # 1. Radiation Exposure: High energy radiation or ionising radiation produces a genetic alteration or mutation at a very low dose also. It has been shown experimentally that a low dose [...]
