psbD sequences of Bumilleriopsis filiformis (Heterokontophyta, Xanthophyceae) and Porphyridium purpureum (Rhodophyta, Bangiophycidae): evidence for polyphyletic origins of plastids.

abstract：:DNA polymerases are evolved to extend the 3'-OH of a growing primer annealed to a template DNA substrate. Since replicative DNA polymerases have a limited role while replicating structurally distorted template, translesion DNA polymerases mostly from Y-family come to the rescue of stalled replication fork and maintain...
