Answer:
The options
A) molecular genetics.
B) epigenetics.
C) behavior genetics.
D) evolutionary psychology.
The CORRECT ANSWER IS B)
B) epigenetics.
Explanation:
Epigenetics is the aspect of biology that deals with heritable changes in gene expression (comparing the active to inactive genes) without any changes to the underlying DNA sequence — a difference in phenotype without any difference in genotype — as it influences how cells read the genes.
Epigenetic change is a usual and essential event but can also be affected by varying factors such as age, the environment/lifestyle, and disease condition.
Epigenetic modifications can be seen during terminal differentiation of cells to skin cells, liver cells, brain cells, etc. Or, epigenetic change can have a negative impact that can lead to diseases such as cancer.
DNA methylation, histone modification and non-coding RNA (ncRNA)-associated gene silencing are known to activate and maintain epigenetic change.
