Sex-Specific Silencing of Gene Expression is Known As

Question

Sex-specific silencing of gene expression is known as:
A)X-inactivation.
B)methylation.
C)chromatin remodeling.
D)imprinting.
E)None of the answer options is correct.

Accepted Answer

X-inactivation is the process by which one of the X chromosomes in females is inactivated to compensate for the double dose of X-linked genes present in females compared to males. This silencing of one of the X chromosomes is an example of sex-specific gene expression regulation.
