Answer 1

Question:

what is RNA interference explain how tobacco plants were made resistance to reduce losses due to nemthode infection?

Answer:

A nematode Meloidegyne incognitia infects the roots of tobacco plants which reduce the production of tobacco. The infection can be prevented using RNA interference process which is checked by silencing of specific mRNA due to a complementary ds RNA. The ds RNA binds and prevents translation of the mRNA.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.RNAi may be used for large-scale screens that systematically shut down each gene in the cell, which can help to identify the components necessary for a particular cellular process or an event such as cell division. The pathway is also used as a practical tool in biotechnology, medicine and insecticides.
