The complexity of microRNA function is that
A)microRNAs can be rRNA,mRNA,or tRNA.
B)they range in size from 10 to 10,000 bases.
C)a microRNA type can bind several mRNAs,and an mRNA can bind several microRNAs.
D)it can be acetylated,phosphorylated,or methylateD.

Question

Quizplus · Accepted Answer

The complexity of microRNA function lies in the fact that one microRNA can bind several mRNAs and a single mRNA can also be targeted by several microRNAs. This leads to regulation of complex biological processes, making it difficult to decipher the exact mechanism of microRNA-mediated gene regulation. Choice A and B are incorrect as microRNAs are a distinct class of non-coding RNAs that range in size from 18 to 25 nucleotides. Choice D is incorrect as microRNA modifications are not the reason for their functional complexity.
