The basic process of viral infection and virus replication occurs in 6 main steps. 1  Adsorption-virus binds to the host cell. 2  Penetration-virus injects its genome into host cell. 3  Viral Genome Replication-viral genome replicates using the host's cellular machinery.
Replication = DNA copied into another molecule of DNA. Replication machine uses DNA polymerases, nucleotides (individual DNA bases), and a host of other proteins and RNA to copy DNA in eukaryotic cells. DNA can only be copied in one direction - 5â² to 3â². Transcription = DNA copied into RNA.
