Answer:
False I think sorry if it is wrong
Answer:
microRNAs
Explanation:
Within the cell, there are different types of regulatory non-coding RNAs (ncRNAs) such as microRNAs (miRNAs), small-interfering RNAs (siRNAs), piwi-interacting RNAs (piRNAs), long ncRNAs, etc., which are able to regulate gene expression. miRNAs are evolutionary conserved small ncRNAs (typically 18-23 nucleotides in length) known to inhibit gene expression by base-pairing with complementary target mRNAs, and thus trigger RNA interference (RNAi) pathways (e.g., mRNA degradation, inhibition of translation, etc). These miRNAs form part of a ribonucleoprotein complex named RNA-induced silencing complex (RISC) that acts to trigger RNAi mechanisms.
