RNA editing is an important epigenetic mechanism: It occurs when small RNA molecules act directly on strands of __________ to cleave or splice from them.
A) messenger DNA
B) junk DNA
C) histone
D) methylated DNA
E) messenger RNA

Question

Quizplus · Accepted Answer

RNA editing refers to the process of altering the nucleotide sequence of mRNA after it has been transcribed from DNA. This process can involve the insertion, deletion, or substitution of nucleotides. It is carried out by small RNA molecules that can recognize specific sequences in the mRNA and cleave or splice them. Therefore, the correct answer is E, messenger RNA.
