This is from full length 7, #46.
Basically, the question is asking which of the following is most complementary to a DNA sequence:
A. tRNA
B. rRNA
C. hnRNA
D. mRNA
Obviously both A and B are wrong. I chose hnRNA because this is the sequence that is the primary transcript from a DNA sequence before any splicing or post-transcriptional modifications. mRNA would definitely be similar, but technically hnRNA should be closer to the DNA sequence.
Kaplan says mRNA is the correct answer, for the sole reason that it is "more stable than hnRNA". Yes, it's more stable, but that wasn't in the question.
Is there something I'm missing?
