A DNA strand is lengthened in the 5'-3' direction by DNA polymerase. And this process is known as the elongation.
What are the properties of DNA Polymerase?
Using the DNA template strand and a starting primer, an enzyme known as (DNA-dependent) DNA polymerase creates a new DNA strand in the 5' to 3' direction.
The growing synthesized DNA strand is supplemented by the DNA polymerase with complementary nucleotides one at a time. Base-pairing is the process by which the complementary sets of nucleotides are joined to the bases of the template DNA strand.
Some DNA polymerases also possess 3'-5' exonuclease activity, which checks DNA strands for replication mistakes.
