What is the main function of microRNAs?
Enhance translation
Regulate translation
Inhibit transcription
Promote replication
Answer
Regulate translation is the main function of microRNAs (miRNAs). miRNAs are small non-coding RNA molecules that play a crucial role in gene regulation. They bind to the 3' untranslated region (UTR) of target mRNAs, leading to translational repression or mRNA degradation. This process allows miRNAs to fine-tune gene expression and control various cellular processes, including development, differentiation, and metabolism.
