Question

Which type of enzyme produces siRNA molecules in eukaryotes?

A) Restriction exonucleases
B) DNA restriction endonucleases
C) Dicer enzymes
D) Regulator enzymes
E) RNA polymerase +1

Answer 1

Dicer enzymes are responsible for producing siRNA molecules in eukaryotes, playing a crucial role in the RNA interference (RNAi) pathway and gene expression regulation.

Step-by-step explanation:

The type of enzyme that produces siRNA molecules in eukaryotes is the Dicer enzyme. Dicer enzymes are part of the RNA interference (RNAi) pathway and are responsible for chopping long double-stranded RNA molecules into small interfering RNAs (siRNAs). These siRNAs then combine with other proteins to form the RNA-induced silencing complex (RISC), which targets messenger RNA (mRNA) for degradation, ultimately reducing gene expression.
