6.
What is one difference between binary fission and the lytic cycle?
a)
binary fission is bacterial reproduction and the lytic cycle is viral rerplication
b)
binary fission is viral replication and the lytic cycle is baterial reproduction

There is very little difference between the 2 processes
7.
What roll does a host play in viral reproduction
