Dicer

Dicer is an enzyme found in cells that plays a key role in gene regulation. It acts like molecular scissors, cutting long strands of a genetic material called RNA into smaller pieces known as small interfering RNAs (siRNAs) or microRNAs (miRNAs). These small pieces help control which genes are active or inactive by guiding other proteins to target specific messenger RNAs (mRNAs), preventing them from producing certain proteins. In this way, Dicer contributes to the regulation of gene expression, impacting processes like development, cell function, and immune response.
