What is the primary method of miRNA action?
Protein binding
Base-pairing
Lipid interaction
Carbohydrate binding
Answer
Base-pairing is the primary mechanism of miRNA action. miRNAs are small, non-coding RNA molecules that regulate gene expression by binding to the 3' untranslated region (UTR) of target mRNAs. This binding typically results in translational repression or mRNA degradation, effectively silencing the expression of the target gene.
