Flashcards in Viruses Deck (7):
1

How can a virus enter the body?

skin, genital tract, respiratory tract

2

Describe how a virus enters the body

Virus envelope fuses with the plasma membrane of the host cell. The viral nuclear material is then released into the host cell

3

Describe the self assembly of a virus

The viral proteins form a viral coat, which forms around the genome. The capsids then assemble and a virus is formed

4

Describe the replication of a virus

A virus attaches and enters a host cell. The virus takes over the host cells metabolism, and protein translocation on ribsosomes occurs.The virus then forms, and is released by either budding or cell apoptosis

5

Why does a virus require a host cell

To make copies of the virus' genetic material and to supply the enzymed needed for replication

6

Give an example of a virus that causes pneumonia

Adenovirus and influenza

7

Give an example of a virus that causes STD

hiv and herpes
