It can be used in developing therapies for the treatment of cancer. III. It can be used to develop hormone replacement therapies. IV. It can be used to produce crop plants that are resistant to viral pathogens. Select the correct answer using the codes given below:

Question

CollectorBabu · Accepted Answer

Correct Answer: 1, 2 and 4. With reference to ‘RNA interference (RNAi)’, statement 1, 2 and 4 are correct. RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is a conserved biological response to double-stranded RNA that mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes. This natural mechanism for sequence-specific gene silencing promises to revolutionize experimental biology and may have important practical applications in functional genomics, therapeutic intervention, agriculture and other areas. There’s no application of RNAi in developing hormone replacement therapies. Hence, statement 3 is incorrect.
