Question

How did mosquitoes develop a resistance to DDT

Answer 1

by opening up the 'active site' where DDT molecules bind to the protein, so more can be broken down.

Answer 2

hope it will help you

Step-by-step explanation:

X-ray crystallography of the protein coded by the gene illustrated exactly how the mutation conferred resistance, by opening up the 'active site' where DDT molecules bind to the protein, so more can be broken down. This means that the mosquito can survive by breaking down the poison into non-toxic substances.
