Discovering that early life stress may cause polymorphisms that increase the risk of depression would be an example of:
A) epigenetics.
B) transcription factors.
C) a Mendelian disease.
D) ribosome transcription.

Question

Quizplus · Accepted Answer

Epigenetics refers to changes in gene expression that occur without changes to the DNA sequence itself. Early life stress can cause epigenetic changes that increase the risk of developing depression later in life. Polymorphisms are variations in the DNA sequence that can also contribute to increased risk of disease. However, in this case, the question specifically mentions that the stress causes the polymorphisms, suggesting an epigenetic mechanism. The other choices are not applicable to this scenario.
