Viruses

Question 1

Common structure of virus

Answer 1

Genetic material enclosed by a capsid (protein) with attachment proteins on outside and sometimes surrounded by lipid envelope

Question 2

What can the genetic material in a virus be like?

Answer 2

DNA or RNA

Question 3

Attachment proteins

Answer 3

To attach to cells and then enter host cell

Question 4

Lipid envelope

Answer 4

Formed from phospholipid belayer of the host cell they attached to

Question 5

Do viruses reproduce?

Answer 5

No because they are non living

Question 6

How do viruses multiply?

Answer 6

In virus replication using host cells by injecting their genetic material into host cell

Question 7

Step 1 of virus replication

Answer 7

Attachment proteins attach to host cell’s receptor proteins

Question 8

Step 2 of virus replication

Answer 8

Virus injects its genetic material from capsid into host cell

Question 9

Step 3 of virus replication

Answer 9

Genetic material is used to encode more capsid and attachment proteins
Then genetic material replicated using cell’s enzymes and ribosomes

Question 10

Step 4 of virus replication

Answer 10

Golgi apparatus assembles new virus

Question 11

Step 5 of virus replication

Answer 11

All viruses are replicated until it bursts and can spread through host’s body

Question 12

Why are viruses no living?

Answer 12

Do not respire
Are acellular
Do not reproduce
