Which is NOT an example of an epigenetic phenomenon?
A)X chromosome inactivation
B)histone methylation patterns
C)sequence of distal promoter elements
D)localization of histone variant CENP-A
E)covalent modification of DNA

Question

Quizplus · Accepted Answer

The sequence of distal promoter elements is a genetic phenomenon, not an epigenetic one. Epigenetic phenomena involve modifications to DNA or associated proteins that can alter gene expression without changing the underlying DNA sequence. X chromosome inactivation, histone methylation patterns, localization of histone variant CENP-A, and covalent modification of DNA are all examples of epigenetic phenomena.
