Question 0

How do viruses reproduce

Answer 0

Invades a living cell

Question 1

What is a virus

Answer 1

Non-cellular, lifeless particle, isn’t in any of the kingdoms and can’t make its own energy .

Question 2

How many groups of viruses are there

Answer 2

165

Question 3

What group of viruses attacks bacteria

Answer 3

Bacteriophages

Question 4

Viruses are made up of 2 parts

Answer 4

Genetic material is DNA or RNA

Capsid (protective protein coat)

Question 5

How big are viruses

Answer 5

10- 400 nm

Question 6

What shape are viruses

Answer 6

They take on many shapes

Question 7

What is the magnification of low, medium and high on a microscope in class

Answer 7

40x, 100x, 400x

Question 8

What happens in the Lytic cycle

Answer 8

The virus attaches to a cell, injects the DNA/RNA into cell. The host cell makes copies of DNA/RNA and new virus capsids, the cell assembles the virus particles. Host cell bursts and releases new virus particles.

Question 9

What is the lysogenic cycle

Answer 9

Virus attaches to cell, inserts DNA/RNA into cell. DNASE inserted/incorporated into cell’s DNA a. Cell divides (mitosis) and new cells produced contain viral DNA. Viral DNA is released and causes the cell to make new viruses, cell erupts(death of cell, stress) and releases viral particles
