Viral Replication

Question 1

Once the virus is inside the host cell, what 2 different process may occur ?

Answer 1

Lytic or Lysogenic cycle

Question 2

Replicates immediately, killing the host cell, fast cycle , immediate symptoms

Answer 2

Lytic cycle

Question 3

A way that does not kill the host cell immediately, slow cycle

Can switch to lytic

Answer 3

Lysogenic

Question 4

In a ___ infection, a virus enters a cell, makes copies of itself, and cause the cell to burst (lyse)

Answer 4

Lytic

Question 5

What are the lytic cycle steps ?

Answer 5

1) attachment - virus recognizes and attaches to host cell
2) entry- viral DNA injected into cell
3) Replication- viral genes and capsids copies
4) Assembly -viral genes put together ono protein coat
5) Lysis (burst) and realize -cell burst and releases viral particles

Question 6

Unlike lytic viruses,____ viruses do not lyse the host cell right away . Instead they remain inactive until the time comes

Answer 6

Lysogenic

Question 7

Lyse means

Answer 7

Burst

Question 8

Lysogenic cycle

Answer 8

1) attachment and entry
2) provirus formation - viral DNA embedded into host cell’s DNA
3) DNA Replication- viral DNA copied along with hose DNA
4) cell division- cell divides with viral DNA
5) lytic cycle -at any time the viral DNA leaves the host DNA and enters the lytic cycle
