What happens in the lytic cyle?

• Virus goes in and leaves the host cell
• Virus quickly kills the host cell
• Virus sleeps inside of the host cell
• Virus stay dormant for a long time

What happens in the lysogenic cycle? 

• Virus goes in and leaves the host cell
• Virus quickly kills the host cell
• Virus inject the nucleic acid into the host cell, and the nucleic acid integrates into the host cell DNA, and stay dormant for a long time
• Bacteria injects DNA into a host cell

The lytic cycle takes the longest out of the two viral reproductive cycles. 

• True
• False

What process is this?

• phagocytosis
• lytic cycle
• lysogenic cycle
• formation of antibodies
