A modification that occurs to a nuclear gene that alters gene expression, but not permanently, is called ________ inheritance.

B) cytoplasmic
C) maternal effect
D) epigenetic
E) nuclear

Question

Quizplus · Accepted Answer

Epigenetic inheritance involves modifications to DNA that alter gene expression without permanently changing the DNA sequence. These modifications can be reversible and can occur in nuclear genes. Extranuclear and cytoplasmic inheritance involve the transmission of genetic material from outside the nucleus (such as mitochondria). Maternal effect inheritance involves the distribution of maternal gene products to offspring during development. Nuclear inheritance is a general term that simply refers to the inheritance of genetic material contained within the cell nucleus.
