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.
What are the reasons that replication occurs. for growth, repairing injuries, reproduction, maintenance, when cells get too large, and to fight illness. What are the steps of replication>. -DNA helix unwinds and unzips (breaks the hydrogen bonds) and the enzyme helicase does this. -DNA nulceotides join (base pair) with DNA bases on both parent strands using the enqyme DNA polymerase. -The strands rewind and rezip so they can be used over again.
