| Description: Table 20.1 Steps in Most Viral Replication Cycles 1. Attachment Proteins on viral particle chemically recognize and lock onto specific receptors at the host cell surface. 2. Penetration Either the viral particle or its genetic material crosses the plasma membrane of a host cell and enters the cytoplasm. 3. Replication and synthesis Viral DNA or RNA directs host to make viral nucleic acids and viral proteins. 4. Assembly Viral components self—assemble as new viral particles. 5. Release The new viral particles are released from the cell.
