Identify the correct answer with respect to RNA interference (RNAi)
P. It is an event of post-transcriptional gene silencing
Q. It works through RNA induced silencing complex
Options:
Answer:
Solution:
RNAi takes place in all eukaryotic organisms as a method of cellular defense. This method involves the silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA (silencing). Since it involves the silencing of mRNA, it is a post-transcriptional gene silencing method. The source of this complementary RNA could be from infection by viruses having RNA genomes or mobile genetic elements (transposons) that replicate via an RNA intermediate. It is a mechanism for fine-tuning normal gene expression during development, apoptosis and other processes.
