WebA DNA virusis a virus that has DNA as its genetic material and replicates using a DNA-dependent DNA polymerase. The nucleic acid is usually double-stranded DNA but may also be single-stranded DNA. The DNA of DNA viruses is transcribed into mRNA by the host cell. The viral mRNA is then translated into viral proteins.

How DNA Replication Works: A Simple Guide

WebNational Center for Biotechnology Information WebJun 14, 2004 · During replication, the strands are unzipped and each is copied following the base-pairing rule. So if there is an A, when you make the copy, you should put in a T and vice versa. The same holds true for G and C. When replication is complete, each new DNA contains one old and one new strand or one parental and one daughter strand.
