Answer:
The methods by which DNA molecules multiply is known as REPLICATION
Explanation:
DNA REPLICATION.-
In all living organism DNA replication occurs. IN replication DNA replicates in this way making its replica or we can say its copy.
During replication, both the strands of DNA are separated first. Then each DNA strand function as the template and makes its own copy to make the full DNA molecule. This is the SEMICONSERVATIVE mode of replication. In which each DNA molecule has one parent strand and one newly synthesized strand.
The replication start sight is ORIGIN OF REPLICTION( in E.coli ori c). At this location Helicase enzymes help in opening of the DNA.
The enzyme which has very unique function of adding nucleotide on the DNA strand and synthesizing DNA is DNApolymerase.
DNA replication occurs in 3' to 5' direction.
