Answer 26

RNA

Question 27

The virus that causes AIDS which is called HIV also contains (blank)

Answer 27

RNA

Question 28

Name step 1 in the lytic cycle

Answer 28

The virus finds and joins itself to a host cell

Question 29

Name step 2 in the lytic cycle

Answer 29

The virus enters the cell or the virus’s genetic material is injected into the cell

Question 30

Name step 3 in the lytic cycle

Answer 30

Once the virus’s genes are inside, they take over the direction of the host cell and turn it into a virus factory

Question 31

Name step 4 in the lytic cycle

Answer 31

The viruses break out of the host cell, which kills the host cell. The cycle begins again

Longer

No they just prevent them

Question 35

Virus

Answer 35
