WebDNA viruses have a DNA core. The viral DNA directs the host cell’s replication proteins to synthesize new copies of the viral genome and to transcribe and translate that genome into viral proteins. DNA viruses cause human diseases such as chickenpox, hepatitis B, and some venereal diseases like herpes and genital warts. WebMay 31, 2016 · The virus needs to make mRNAs that can be translated into protein by the host cell translation machinery. The virus needs to replicate its genome. Host enzymes for mRNA synthesis and DNA replication are nuclear (except for those in mitochondrion) and so, if a virus is to avail itself of these enzymes, it needs to enter the nucleus.
