Virus Reproduction

Question 1

Lytic Cyle

Answer 1

-Virus attaches to a host cell - attaches to a receptor, which allows it to attach
- virus injects its genetic material inside cells
- some hosts are tricked into recognising the virus
- cell would follow the virus’ instructions to make copies of the virus (make viral proteins)
- cell uses its own resources to make copies of the virus
- this can cause cell membrane to burst/ lyse

Question 2

Lysogenic Cycle

Answer 2

• virus attaches to the host cell
• virus injects their genetic material into the cell, but this time the genetic material is kept hidden in the host cell’s genetic material
• when the host cell makes new cells, it replicates its own genetic material and the virus’ genetic material
• daughter cells then make new cells, replicating their genetic material and the virus’ genetic material
  And so on

Question 3

How can cells containing the virus’ genetic material become dangerous when changing from a lysogenic Cycle to a lytic cycle?

Answer 3

• if a trigger occurs
• this could cause all cells with the virus’ genetic material to assemble viruses and activate
• there’s a variety of triggers in which could cause this: chemical trigger, lack of food etc.
