Dicer is a crucial enzyme in the RNA interference (RNAi) pathway, which plays a significant role in regulating gene expression. This ribonuclease III enzyme is responsible for processing double-stranded RNA (dsRNA) into small interfering RNA (siRNA) and microRNA (miRNA), both of which are essential in silencing specific mRNA targets. Dicer's ability to cleave dsRNA into 20-25 nucleotide fragments is pivotal in various biological processes, including development, differentiation, and disease mechanisms.
