Which of the following events are involved in RNA interference (RNAi)?
Incorporation of pest-specific genes into the virus genome.
Production of complementary RNA strands by pest-specific genes.
Expression of protoxins in plant tissues.
Pesticides targeting infested plant cells.
Answers (1)
In RNA interference (RNAi), one of the key events is the production of complementary RNA strands by pest-specific genes. These complementary RNA strands, also known as small interfering RNAs (siRNAs), can bind to and target specific messenger RNA (mRNA) molecules, leading to their degradation and subsequent silencing of the corresponding genes. This process is crucial in regulating gene expression and can be used as a mechanism to combat pests by specifically targeting their essential genes. The other options listed, such as the incorporation of pest-specific genes into the virus genome, expression of protoxins in plant tissues, and the use of pesticides, are not directly related to RNA interference.
Hence, the correct answer is option 2
