31. This contrasts with latency, in which host cell DNA polymerase copies the viral genome. 32. The resultant gap is then filled in using DNA polymerase I and DNA ligase. 33. Unfortunately once the primer is removed, DNA polymerase is unable to synthesize the remaining bases. 34. Some virus es also encode special DNA polymerases, such as Hepatitis B virus DNA polymerase . 35. Reverse transcriptase is the virally encoded RNA-dependent DNA polymerase . 36. So I focused on Hepatitis B virus DNA polymerase . 37. Helicases unwind the strands to facilitate the advance of sequence-reading enzymes such as DNA polymerase . 38. Next, DNA polymerase III ( green ) produces the leading strand copy ( red ). 39. The strand is then re-synthesized by DNA polymerase III. 40. Transpovirons encode a superfamily 1 helicase, which encompasses an inactivated family B DNA polymerase domain.
