Which of the following statement is incorrect w.r.t. pest resistant plants RNA interference?
RNAi silences the pest target genes by methylation of the target DNA sequence.
The dsRNA expressed in the plant is specific to a vital gene of the insect pest.
The dsRNA is processed into siRNA which then degrades the mRNA of the pest.
RNAi technique has been used to develop pest-resistant plants in several crops like cotton and tobacco.
