Epigenetics Regulatory Mechanism Essay

Epigenetics is a regulatory mechanism of human gene that affects the differentiation of a cell and human development. All cells in the body are genomic identical but they differentiate to ensure normal functioning of body components such as skin, neurons, and enzymes. Nonetheless, the normal cell differentiation is influenced by various external factors such as diet, exercise, environmental exposure, aging and illnesses such as cancer. These factors have both positive and negative effects in the gene function epigenetically (Shukla, & Meeran, 2014, p.2). The video Epigenetics shows how modification of the DNA or other protein related to DNA influences the activity of the genes. For instance, proteins such as histones can take place in modification mechanisms such as phosphorylation, methylation, and acetylation. Enzymes such as “writers” add modifications to histones while “eraser” enzymes remove the modifications. Moreover, proteins known as “readers” are able to identify the particular modifications
