Which of the following pairs is incorrect?
1 Plasmid-small piece of extra-chromosomal DNA is bacteria
2 Elution-removal of proteins digested by protease.
3 Cosmid - a vector for carrying large DNA fragments into host cells
4 Protoxin Cry protein is changed into active Cry protein in the stomach of insects due to alkaline \(\mathrm{pH}\) in stomach
Explanation:
Bands of DNA separated during gel electrophoresis are cut out from the agarose gel and extracted from the gel piece which is called as Elution.

In \(B t\) cotton, the \(B t\) toxin present in plant tissue as pro-toxin is converted into active toxin due to
1 Presence of conversion factors in insect gut
2 Action of gut micro-organisms
3 Acidic \(\mathrm{pH}\) of the insect gut
4 Alkaline \(\mathrm{pH}\) of the insect gut.
Explanation:
\(B t\) toxin are solubilised in alkaline \(\mathrm{pH}\) of the insect gut causing death.
