Choose wrong statement with respect to RNA interference. (a) RNAi takes place in all eukaryotic organisms as a method of cellular defense (b) RNAi involves silencing of a specific m- RNA due to a complementary ds DNA (c) Source of complementary RNA may be mobile genetic elements (transposons) that replicate via an RNA intermediate (d) Introduction of DNA produced both sense and anti- sense RNA in host cells.
Option B.RNAI or RNA interference takes place in all eukaryotic organisms as a method of cellular defense. This method involves silencing of a specific mRNA. Using Agrobacterium vectors, nematode-specific genes are introduced of DNA was such that it produced both sense and anti-sense RNA in the host cells. These two RNAs being complementary to each other formed a dsRNA (double-stranded RNA) that initiated RNAI.
