What is the impact of miRNA on messenger RNAs?
Destroys them
Regulates them
Copies them
Ignores them
Answer
Regulates them. MicroRNAs (miRNAs) are small non-coding RNA molecules that play a crucial role in regulating gene expression. They bind to the 3' untranslated region (UTR) of messenger RNAs (mRNAs), which are the templates for protein synthesis. This binding can either prevent the translation of the mRNA into protein or cause its degradation, effectively reducing the expression of the corresponding gene.
