Sense strands: It is a coding strand which carries translatable code directed in the 5' to 3' direction and contains codons.

Anti sense strand: It is complementary strand to the sense strand which is non coding strand and contains anti-codon.

Because it ensures hydrogen bonding between the nitrogenous bases lying opposite to each other.

Enzymes for DNA replication with roles :

Endonuclease: nicking

Helicase : breaking hydrogen bond

Phosphorylase : activation of phosphate group

Topoisomerase: release pressure during fork formation

Ligase : joining fragments

RNAse : help in okazaki fragment formation

Restriction endonuclease: checking

Process of semi-conservative mode of replication of DNA:

The mechanism of DNA replication is a complex and involves many steps. The steps are:

1) Initiation of DNA replication

2) Activation of deoxyribonucleotides

3) Exposure of DNA strands or nitrogen bases and formation of Y-shaped fork

4)Formation of RNA primer

5) Base pairing

6) Formation of new DNA strands

7)Proof-reading and DNA repair

8)Termination of DNA helix formation.

1)Initiation of DNA replication-
