Zoology - Biotechnology and Its Applications Question with Solution | TestHub

This is gene subtraction. This method is used to change the genotype of a plant by either inactivation or removal of the gene. A nematodeMeloidogyne incognitainfects the roots of tobacco plants causing a great reduction in yield. The strategy adopted to prevent this damage was the RNA interference process (RNAi). RNAi is a naturally occurring mechanism that causes 'silencing' of the genes. This method involves silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevent translation of mRNA.
