Question

RNA interference (RNAi) helps in making tobacco-plant resistant to a nematode (Meloidegyne incognitia)

Choose the correct option that shows how RNAi is achieved:

Options

• Preventing the process of translation of mRNA of the nematode.

• Preventing the process of replication of DNA of the nematode.

• Preventing the process of transcription of DNA of the plant.

• Preventing the process of replication of DNA of the plant.

Answer 1

Preventing the process of translation of mRNA of the nematode.

Explanation:

A gene-silencing technique known as RNA interference (RNAi) stops the expression of particular genes by breaking down their mRNA prior to translation. By generating double-stranded RNA (dsRNA) that is complementary to the worm’s mRNA, RNAi targets the Meloidogyne incognita nematode in genetically modified tobacco plants. This inhibits nematode survival by causing mRNA degradation and blocking the synthesis of vital proteins.
