RNA interference (RNAi) technology is being explored for developing pest-resistant plants. Which statement about RNAi is INCORRECT?
The RNAi effect can be highly specific to the target pest.
The introduced dsRNA is processed into smaller interfering RNAs (siRNAs).
RNAi primarily works by blocking translation of target mRNA.
The RNAi trait is easily inherited through traditional plant breeding methods.

Study the following statements regarding Bt toxins produced by bacterium Bacillus thuringiens is and select the correct one
Some strains of Bacillus thuringiens is produce proteins that kill certain insects such as lepidopterans, coleopterans and dipterans
Bt toxin proteins do not kill the bacteria themselves because the toxin proteins occur in an inactive form called protoxins
When an insect ingests the inactive Bt toxin, it is converted to an active form of toxin due to alkaline pH of the gut which solubilises the protein toxin crystals
