Question

Which enzyme is responsible for the synthesis of microRNAs?

(a) enhancer

(b) dicer

(c) splicer

(d) promoter

I had been asked this question in final exam.

I'd like to ask this question from Gene Expression Control in section Control of Gene Expression of Cell Biology

Answer 1

Right answer is (b) dicer

To explain: Dicer is the enzyme that brings about the synthesis of microRNAs. Since miRNAs play an important role in translational-level control, absence of dicer influences the growth and development of a specific compound.
