Viruses

Question 0

Describe the crystal shaped virus

Answer 0

Multi-sided geometric look

Question 1

Name the four shapes of viruses

Answer 1

Crystals, spheres, cylinders, spacecraft

Question 2

Describe the sphere shaped virus

Answer 2

Rounded shape with small projections or bumps on the outside of the particle

Question 3

Describe the cylinder shaped virus

Answer 3

Rod or cylinder shaped

Question 4

Describe the spacecraft shaped virus

Answer 4

Bacteriophage viruses look like this, and the viruses in this group look like a spaceship

Question 5

What is step 1 of the lytic cycle?

Answer 5

The virus uses its protein coat to locate an appropriate host. The virus attaches its tail fibers to the outside of the host cell

Question 6

What is step 2 of the lytic cycle?

Answer 6

The virus then injects its genetic material (DNA&RNA) into the host cell through the host cell’s membrane

Question 7

What is step 3 of the lytic cycle?

Answer 7

Then the viruses hereditary material takes control of the host cell and all of the host cell’s activities. The host no longer controls its own life processes. The host cell is used to make new viral particles.

Question 8

What is step 4 of the lytic cycle?

Answer 8

Eventually the new viruses assemble and the host cell fills up with the newly formed and complete viruses

Question 9

What is step 5 of the lytic cycle?

Answer 9

Finally the viruses burst out of the host cell each to go and attack another host cell. The above process continues until fighter cells in the host organism can stop the viral particles or until the viral particles damage and kill the organism
