A replicating DNA polymerase is an enzyme that extends a paired strand end with nucleotides selected against a DNA template. New DNA grows while the template is read . Base pairing specifies the partner; the DNA polymerase catalyzes its incorporation. See Alberts et al.: DNA polymerase.
An E. coli polymerase participating in primer removal and gap filling, distinct from the principal chromosomal replicase DNA polymerase III.
A eukaryotic replicative polymerase with a predominant lagging-strand role, also participating in initiation, strand displacement and repair contexts.
A eukaryotic replicative polymerase with a predominant leading-strand role during conventional nuclear replication.
The eukaryotic initiation complex that synthesises an RNA primer and then a short DNA extension before handoff to more processive polymerases.
The principal E. coli chromosomal replicative DNA polymerase, operating with a sliding clamp and associated replication factors.
Taq polymerase is a heat-resistant DNA polymerase used in PCR amplification. It requires a paired strand end and nucleotide substrates; heat resistance does not confer target recognition.
