Which of the following statement is not in relation to more selection of pesticide - resistant microbes?
Answers
Answer:
Correct option is
B
The choice of gene depends upon the crop and the targeted pest, as most Bt-toxins are insect
Bt-toxin is produced by a bacterium called Bacillus thuringiensis and Bt-toxin protein exists as inactive protoxin but once an insect ingest due to alkaline pH it become active. Bt-cotton helped to reduce post harvest losses. However, the choice of gene does not depend upon the crop and the targeted pest as most Bt-toxins are not insect specific.. Cry toxins have specific activities against insect species of the orders Lepidoptera (moths and butterflies), Diptera (flies and mosquitoes), Coleoptera (beetles), Hymenoptera (wasps, bees, ants and sawflies) and against nematodes.
So the correct option is 'The choice of gene depends upon the crop and the targeted pest, as most Bt-toxins are insect'.
The answer is B I think is this a crct answer or not tell
