Topic 2- Viral particle replication

Question 1

Why do viruses not undergo cell division?

Answer 1

They are non living

Question 2

What does parasitic mean?

Answer 2

they can only reproduce by infecting living cells (known as host cells)

Question 3

How do viruses replicate?

Answer 3

injecting their nucleic acid into a host cell

Question 4

1st step of Viral replication

Answer 4

uses attachment proteins on its surface to bind to complementary receptor proteins on the surface of a host cell

Question 5

2nd step of Viral replication

Answer 5

injects its DNA or RNA into the host cell

Question 6

3rd step of Viral replication

Answer 6

The host cell then uses its nucleic acid and ribosomes to produce new viral particles

Question 7

4th step of Viral replication

Answer 7

new viral particles are released

Question 8

When are the new particles released?

Answer 8

-The host cell bursts open, releasing all the new viral particles at once
-Viral particles leave individually through the host cell membrane via a process known as ‘budding’, often taking a section of the membrane with them
