Step-by-step explanation:
Viruses host particles of either DNA or RNA that is surrounded by a(n) capsid
made of proteins. A(n) envelope that was part of a(n) infectious
cell´s cell membrane covers some types of viruses.
The bacteriophage viruses that infect bacteria, have a complex structure that includes a ¨head¨ and a ¨tail¨. All viral disease occurs only within living cells.
reproduction occurs only within living cells.
virus can reproduce immediately by the lytic cycle, or they can enter the lysogenic cycle and be inactive as a(n) prophage within a bacterial chromosome. Viruses that infect animals, such as HIV which causes AIDS, have much more complex cycles of reproduction.
