Question

In RNA inerference studies, the double-stranded RNA

a) disrupts the target DNA sequence
b) results in the destruction of the target mRNA
c) destroys the target protein
d) all of the above

Answer 1

Answer:

b) results in the destruction of the target mRNA

Explanation:

RNA inerference  -  

It is the process , when the molecules of RNA , inhibits the gene expression or the translation process , via neutralizing targeted mRNA molecules .

During the process of RNA inerference , the target mRNA is destroyed .

hence , from the given options the correct statement for RNA  inerference is ( b ) .

Answer 2

Question:

A researcher conducted studies on proteins obtained from mouse livers. He discovered a novel protein and decided to obtain its genetic origins. The mRNA sequence he found was AUUCGGUACUGUACUAGC. What is the sequence of the DNA strand that was used for RNA synthesis?

A. TTTGCTATACTATAGTAC

B. ATTCGGTACTGTACTAGC

C. TAAGCCATGACATGATCG

D. ATGTCTATACTAGCTTTT
