Which enzyme, also responsible for siRNA formation, carves miRNAs from their double-stranded, fold-back RNA precursor (pre-miRNA)?
A)RNA polymerase
B)reverse transcriptase
C)Dicer ribonuclease
D)Drosha polymerase
E)Mincer ribonuclease

Question

Quizplus · Accepted Answer

Dicer ribonuclease is responsible for carving miRNAs from their double-stranded, fold-back RNA precursor (pre-miRNA). Dicer is also responsible for siRNA formation. RNA polymerase is involved in transcription, reverse transcriptase is involved in converting RNA to DNA, and Drosha polymerase and Mincer ribonuclease are not enzymes involved in miRNA processing.
