검증된 단계별 안내1
Understand that mRNA transcripts undergo several modifications after transcription to become mature mRNA ready for translation.
Recall that one common modification is the addition of a poly-A tail at the 3' end of the mRNA transcript.
Recognize that the poly-A tail is composed of multiple adenine nucleotides added enzymatically.
Note that this tail is important for mRNA stability, nuclear export, and translation efficiency.
Conclude that the tail is made up of adenine nucleotides, not cytosine, uracil, or guanine.
