Question

RNA interference which is employed in making tobacco plant resistant to Meloidegyne incognita is essentially involved in

• A. preventing the process of replication of DNA
• B. preventing the process of translation of mRNA
• C. preventing the process of splicing of hnRNA
• D. preventing the process of transcription

Answer 1

The correct option is B preventing the process of translation of mRNA

RNA interference is a gene-silencing process that blocks the expression of genes in the parasite when it enters the host's body.RNA is a method adopted to prevent infestation of roots of tobacco plants by a nematode Meloidogyne incognita. In RNA, a complementary RNA binds to mRNA to form a ds RNA that cannot translate and hence, its expression is blocked.

So, the correct option is 'Preventing the process of translation of mRNA'.
