The process of epigenetics involves chromatin remodeling, a process that involves the modification of the DNA methylation and histone (Burrggrreen, para 1). Burrggrreen adds that the process occurs alongside RNA-mediated modifications and involves self-sustenance loops and structural inheritance (Ho DH 3). There are particular reasons why the study of epigenetics is important today (Suter and Aagaard-Tillery, para 45). They add that pollution and global climate change in relation to global warming means that the human race needs to survive in the continually changing environment. This is in relation to what the two articles by Burrggrreen and Feero et al. have discussed- the body will need to alter its genetic sequence so that it can be able to handle the dangers that both our genetic makeup and environmental changes present.
The process of epigenetics occurs without the modification of the gene sequence. The idea of epigenetics has not been fully embraced partly because it is not a part of physiological investigations (Feero et al., para 4). Any change in environment continually affects the subsequent generation since there is suppressing or expressing a certain character. This expressing or silencing of gene does not affect the gene sequence for at least some generations (Burrggrreen, para 1).
The understanding of the role played by epigenetic changes in regulating the expression or silencing of genes has seen significant advancement over the past decade. These changes are simple chemical alterations in the DNA that do not affect the chief base-pair sequence of the DNA. In the aforementioned DNA methylation involves enzymatic methylation of the cytosine nucleotides that are found in some regions of the DNA. The transcription does not occur ...Download file to see next pagesRead More
