Which of the following are molecular mechanisms used in epigentic gene regulation?
A) DNA methylation
B) Covalent histone modification
C) Chromatin remodeling
D) All are correct

Question

Quizplus · Accepted Answer

All of the choices (A, B, and C) are correct mechanisms used in epigenetic gene regulation. DNA methylation involves the addition of a methyl group to DNA nucleotides, covalent histone modification involves chemical changes to histone proteins that affect gene expression, and chromatin remodeling involves changes to the physical structure of chromatin, which can affect gene accessibility.
