Question

Answer 1

Answer:

in bad sanitary conditions the virus mainly occur

Answer 2

Answer:

two type ....

1.lysogenic

2.lytic

Explanation:

The structure of viruses allows them to succeed in their main

mission—reproduction.

Lytic Cycle Once attached to a host cell, a virus injects its nucleic

acid into the cell. The nucleic acid takes over the normal operation of the

host cell and produces multiple copies of the virus’s protein coat and

nucleic acid. Once produced, the protein coats and the nucleic acids are

assembled into new viruses. As the host cell fills with newly assembled

viruses, it bursts, just like a balloon with too much air. The host cell then

dies, and the released viruses begin searching for the next host cell. This

type of viral reproduction is called a lytic (LIT ihk) cycle.

.

Lysogenic Cycle Some viruses, such as herpes and HIV, enter the

host cell but remain hidden for years. Even though the viral nucleic acid

becomes part of the host cell’s chromosome, it does not seem to affect

the functions of the cell. At some point, however, the viral nucleic acid

becomes active. It separates itself from the host cell’s genetic material,

takes over the functions of the cell to produce new viruses, and destroys

the host cell as the new viruses are released. This type of viral

reproduction is called a lysogenic (li suh JE nihk) cycle.
