摘要：

The deduced amino acid sequences of two eukaryotic chlorella virus (PBCV-1 and NY-2A) DNA polymerases are 90% identical and contain amino acid motifs typical of alpha-like (Family B) DNA polymerases. The open reading frames of both PBCV-1 and NY-2A DNA polymerases are interrupted by an identically located, small (101 or 86 nucleotides, respectively) intron that resembles eukaryotic nuclear-spliced messenger RNA introns. This discovery suggests that chlorella virus replication has a nuclear phase. © 1992.
