E) All of the answers are correct.

Question

Quizplus · Accepted Answer

MicroRNAs (miRNAs) are indeed a relatively recent discovery in the field of genetics, first identified in the early 1990s in Caenorhabditis elegans. They are produced from regulatory genes and function by binding to target mRNAs, thereby blocking their translation into proteins, which makes all the provided statements correct.
