Which is not an example of an epigenetic phenomenon?
A)X chromosome inactivation
B)histone methylation patterns

E)covalent modification of DNA

Question

Quizplus · Accepted Answer

The sequence of distal promoter elements refers to genetic information and not epigenetic information. Epigenetic phenomena involve modifications that do not affect the DNA sequence but rather alter how the DNA is packaged and expressed. X chromosome inactivation, histone methylation patterns, localization of histone variant CENP-A, and covalent modification of DNA are all examples of epigenetic phenomena.
