Quizplus · Accepted Answer

The area of research that Dr. Maxwell investigates, particularly the regulation of gene activity and the determination of cell differentiation, aligns with the field of epigenetics. Epigenetics studies heritable changes in gene expression without changes to the underlying DNA sequence, including factors such as chemical modifications to DNA and associated proteins.

Note: 
A) Genetic mutation research focuses on the identification and characteristics of specific mutations and their associated effects. 
B) Zygotic research studies the molecular and genetic events that occur from fertilization through the formation of the zygote. 
D) The human genome project aimed to sequence and map all genes in the human genome, but does not directly relate to Dr. Maxwell's specific research focus.
