Steps in viral replication
Synthesis of Viral Compnents
Types of Penetration:
Period before the start of viral nucleic acid replication.
Period after the start of viral nucleic acid replication.
Viral genes that express before nucleic acid replication
Early Genes encode for….
… enzymes or factors that help in virus replication.
Viral genes that express after nucleic acid replication
Late Genes encode for…
…viral structural proteins and factors for virus assembly.
Attachment, penetration and uncoating have taken place. Synthesis of viral components may have started, but viral assembly has not yet started.
Get out of the cell
Loss of virus infectivity.
