UPSC 2019: 'RNA interference (RNAi) technology has gained popularity in the last few years. Why? 1. It is used in developing gene silencing therapies. 2. It can be used in developing therapies for the treatment of cancer. 3. It can be used to develop hormone replacement therapies. 4. It can be used to produce crop plants that are resistant to viral pathogens. Select the correct answer using the code given below.

Not attemptedCorrect Answer: (a) 1, 2 and 4
RNAi is a naturally occurring gene-silencing mechanism. Scientists harness it (1) as a therapeutic tool to switch off disease-causing genes, (2) to knock down oncogenes in experimental cancer therapies, and (4) to engineer plants that express small interfering RNAs against viral genomes, conferring virus resistance. It is not used to supply exogenous hormones, so statement 3 is wrong. Therefore statements 1, 2 and 4 are correct ⇒ option (a).
