Question

Select the correct answer from each drop-down menu. RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called( ) , which form a complex with RISC and degrade specific ( ) .
1st part
A. Smaller Interfering RNA (siRNA)
B. Single Stranded RNA (ssRNA)
C. Double Stranded RNA (dsRNA)

2nd part
A. Proteins
B. mRNA
C. DNA

Answer 1

The correct answer for 1st part ( A) Smaller Interfering RNA (siRNA) and 2nd part is mRNA

During the whole procedure of RNA interference the long dsRNA is cut down into smaller fragments (nucleotides) by an enzyme called Dicer. These smaller fragments are called as Smaller Interfering RNA (siRNA) to bind to proteins. This Smaller Interfering RNA forms complex with RISC and helps in degradation of mRNA.
