RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.
siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.
Answer: Option B
Explanation:
The population of moose increased during 1990-1995 because the predators that feed on moose population was low.
The predators that feed on the population of moose are large carnivores which eats them.
This caused increase in the population of moose during 90s as there was a sudden decrease in the population of predators that feed on them.
Apparently it is ATP as deduced from the last line of text and no model to refer to.
