Ans. Option (a).

Genetic engineering involves intentional modification of the characteristics of a target organism by the manipulation of its DNA or genetic material.

It includes five steps: isolation of target gene; formation of recombinant DNA molecule by joining target gene and vector molecule; insertion of recombinant DNA (vector and target DNA) to host cell; production of many copies of recombinant DNA molecule in host cell; separation and purification of target gene product from host body.

Hence, according to given diagram, step 2 describes cutting of target DNA and vector molecule to get desired fragments, which are then ligated with the ligase enzyme to make a recombinant DNA.

Thus, the correct answer is option (a).

Select all of the reactants in cellular respiration. glucose oxygen carbon dioxide water be ATP

vampirchik [111]

A, B, D

Cellular respiration is the process responsible for converting chemical energy, and the reactants/products involved in cellular respiration are oxygen, glucose (sugar), carbon dioxide, and water. While the exact steps involved in cellular respiration may vary from species to species, all living organisms perform some type of cellular respiration. Without cellular respiration, living organisms wouldn’t be able to produce the chemical energy they need
