62. Give one reason why viruses are living and one why they are not
a. They can reproduce, but they cannot live outside of a host
63. Draw the lytic and lysogenic cycle and explain it
Lytic cycle: A virus attaches to the host cell. The virus injects DNA into the host
cell. Cell creates new viral DNA and proteins. The host cell assembles virus.
Cell lyses, releasing viruses.
Lysogenic cycle: A virus attaches to the host cell. The virus injects DNA into the
host cell. Viral DNA inserts itself into host DNA. Cell divides. Stays dormant.
Provirus leaves host cell’s DNA. Cell creates new viral DNA and proteins. The
host cell assembles virus. Cell lyses, releasing viruses.
