Question
Biology Question on the molecular basis of inheritance
Complementary ds RNA which prevents translation is formed in ____.
A
PCR
B
RNA interface
C
Gene therapy
D
ELISA
Answer
RNA interface
Explanation
Solution
RNA interference (RNAi) is a biological process in which small RNA molecules inhibit gene expression or translation by targeting complementary mRNA sequences. The small RNA molecules involved in RNAi are often double-stranded (dsRNA) and are designed to be complementary to the target mRNA. When these dsRNA molecules bind to the target mRNA, they can prevent its translation into protein, effectively silencing the gene.
So, the correct option is (B): RNA interface.
