A modification that occurs to a nuclear gene that alters gene expression without modifying the DNA sequence is called ________ inheritance.
A) extranuclear
B) cytoplasmic
C) maternal effect
D) epigenetic
E) nuclear

Question

Quizplus · Accepted Answer

Epigenetic inheritance refers to changes in gene expression that occur without changing the DNA sequence itself, such as modifications to DNA bases or alterations to histone proteins. These inherited changes can be influenced by factors such as environmental conditions or maternal behavior, and can be passed down to subsequent generations. The other choices (extranuclear, cytoplasmic, maternal effect, and nuclear) do not specifically refer to modifications that alter gene expression without changing the DNA sequence.
