Question

During replication DNA deoxynucleotides are added one by one in 5'to 3' end direction by phosphodiester band formation. In this process of polymerisation, the source of energy is
1) ATPs 2) GTPs. 3) dNTPs. 4) NADH2

Answer 1

In this process of polymerisation, the source of energy is 3) dNTPs

• A number of enzymes and proteins are used during the process of replication of DNA.
• One such enzyme is the DNA polymerase. The DNA polymerase adds nucleotides to the new strand of the DNA one by one due to which a new strand is created.
• The energy to carry out this polymerisation comes from the dNTPs which are ATP, GTP,CTP AND TTP.

Answer 2

Explanation:

During replication DNA deoxynucleotides are added one by one in 5'to 3' end direction by phosphodiester band formation. In this process of polymerisation, the source of energy is

3) dNTPs.
