Viruses

Question 1

What is a capsid

Answer 1

Similar to a nucleus
Contains virus’s genetic material (this could be DNA or RNA)

Question 2

What is the viral envelope

Answer 2

Made from fatty lipid molecules which are taken from cells in the host
It protects the inside of the cell

Question 3

What are attachment proteins

Answer 3

Help the virus recognise and bind to cells in the host organism

Question 4

What is viral genetic information

Answer 4

DNA or RNA
Contains the information for making new copies of the virus

Question 5

Stage 1 of the virus lifecyle

Answer 5

Once the virus particle reaches a vulnerable host cell, it attaches to it using surface proteins

Question 6

Stage 2 of the virus lifecyle

Answer 6

The virus genetic information (DNA or RNA depending on the virus) goes inside the host cell

Question 7

Stage 3 of the virus lifecyle

Answer 7

The virus DNA or RNA takes over the host cell machinery and makes lots of copies of itself

Question 8

Stage 4 of the virus lifecyle

Answer 8

After the virus has replicated, the new virus particles break from the host cell and can go on infecting more cells
