For the replictn of nuclic acid if it is DNA then hydrogen bonds shud b broken by helicase enzyme aka rep enxe then single standard DNA is destabilized by another enzyme then RNA primer binds to ss DNA further polymerisation continues by DNA polymerase enzyme in 1 of the stand while on other strand okazaki fragments are formed which need RNA primer every time.
Then d fragments r joint by DNA ligase n two replica are formed.

DNA Replication is a process of generation of a new dna molecule. It is prerequisite at the time of cell division. Basic idea of dna replication is that the new dna molecule formed should be exactly identical from the parent dna Different enzymes are required for this work. First of all the hydrogen bonds of dna are broken and then the dna molecules are well seperated with a incision.


1) Initiator Proteins- Helps in breaking H bonds.

2) Helicase - Helps in seperation of strands.

3) SSBP- Prevents coiling of DNA

4) RNA primase- for formation of primer(small nucleotide sequence)

5) DNA Polymerase- Polymerisation of dna molecules.
