Because they act to _______ tumorigenesis,the miR-15a and miR-16 miRNAs can be thought of as _________.

Question

Quizplus · Accepted Answer

The question mentions that miR-15a and miR-16 act to "inhibit" tumorigenesis, which implies that they work to suppress the development of tumors. Therefore, they are likely tumor suppressors. Choice D is the only option that correctly identifies them as tumor suppressors. Choices A and C both suggest that they enhance tumorigenesis, which is the opposite of what the question stated. Choice B suggests that they are oncogenes, which are genes that can promote cancer development when mutated or overactive. This contradicts the statement that miR-15a and miR-16 inhibit tumorigenesis. Choice E is unrelated to the question and refers to a different concept entirely.
