dsRNA is used to develop pest resistant tobacco plant by a technique called:
1 Polymerase Chain Reaction (PCR)
2 RNA interference (RNAi)
3 Electrophoresis
4 Insertional Activation
Explanation:
Meloidogyne incognita (a nematode) infects the roots of tobacco plants leading to big losses in crop yield. To prevent this infestation, a novel technique based on the process of RNA interference (RNAi) or post transcriptional gene silencing (PTGS) has been adopted.

When DNA is transcribed into mRNA, usually the mRNA remains single-stranded, but in some cases an RNA can be made that is complementary to the mRNA. This is called ____ and its main function is to ____
1 Antisense RNA, block gene expression
2 Antisense RNA, amplify mRNA
3 Antisense RNA, enhance translation
4 Reverse transcription, enhance translation
Explanation:
When DNA is transcribed into mRNA, usually the mRNA remains single-stranded, but in some cases an RNA can be made that is complementary to the mRNA. This is called Antisense RNA and its main function is to block gene expression.
