Question

Write the dual purpose served by Deoxyribonucleoside triphosphates in the polymerisation.

Answer 1

Explanation:

1. serves as substrate to the reaction
2. provides energy to polymerization reaction i.e energy source

Answer 2

Answer:

Explanation is given below

Explanation:

Deoxyribonucleoside triphosphates (DNTPs) consist of a deoxyribose sugar, a nitrogenous base (adenine, guanine, thymine or cytosine) and three phosphate groups. DNTPs (dATP, dTTP, dGTP, dCTP) are four different types.

Dual purpose served by Deoxyribonucleoside triphosphates in the polymerization are as follows:

(1) They act as substrates for DNA synthesis.

(2)They provide energy for polymerization reaction. The two terminal phosphates are high-energy phosphates in a deoxyribonucleoside triphosphates.
