Biochemistry
Dicer is an essential enzyme involved in the processing of precursor microRNAs (pri-miRNAs) into mature microRNAs (miRNAs), which are crucial for gene regulation. This enzyme cleaves long RNA molecules into shorter fragments, allowing for the subsequent loading of these miRNAs into the RNA-induced silencing complex (RISC). The action of Dicer plays a vital role in post-transcriptional regulation by modulating gene expression through RNA interference.
