MicroRNAs can regulate gene expression by causing mRNA degradation or blocking translation.
Is it true that MicroRNAs can regulate gene expression by causing mRNA degradation or blocking translation?
Yes. MicroRNAs regulate gene expression post-transcriptionally by binding to target messenger RNAs, leading to transcript degradation or translational repression.
Verdict: SUPPORTED · 7 sources for, 0 against · Last checked
The claim states that microRNAs regulate gene expression by causing mRNA degradation or blocking translation. Multiple retrieved papers explicitly support that microRNAs act post-transcriptionally by targeting mRNAs to suppress their expression and regulate stability.
