Question

Genomic imprinting,DNA methylation,and histone acetylation are all examples of
A)genetic mutation.
B)chromosomal rearrangements.
C)karyotypes.
D)epigenetic phenomena.
E)translocation.

Accepted Answer

Genomic imprinting, DNA methylation, and histone acetylation are all epigenetic phenomena. Epigenetics refers to changes in gene expression that do not involve changes to the underlying DNA sequence, but instead involve modifications to the DNA molecule itself, as well as modifications to associated proteins called histones. These modifications can be heritable and can have a profound impact on gene expression and ultimately on an organism's traits and development.
