What are two roles that dna polymerase has in dna replication?

The two roles that DNA polymerase has in DNA replication are: it breaks down long chains of polymers into amino acids and it is an enzyme, as most biochemical reactions do about enzymes, that is responsible for duplicating copies of DNA in the form of nucleic acid molecules.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
