Question

Quizplus · Accepted Answer

The best choice is D, methylation, because studies have found that high-stress environments can cause changes in DNA methylation patterns in nurses. Methylation is the addition of a methyl group to a DNA molecule, which can change the way that genetic information is expressed. The other options (A, B, and C) are less likely to be affected by environmental factors such as stress.
