Chapter 16

Question 1

Capsid

Answer 1

Protein coat surrounding the genetic material. Shape determines a virus’ overall form

Question 2

Envelope

Answer 2

Outer layer derived from the host’s cell membrane

Question 3

Bacteriophages

Answer 3

Viruses that infect bacteria

Question 4

Host range

Answer 4

The kinds of organisms or cells that a virus can infect

Question 5

Reservoir

Answer 5

The site of a virus where it exists on nature

Question 6

Lytic infection

Answer 6

A virus enters a bacterium, immediately replicates, and causes the host cell to burst as it releases A flood of new viruses

Question 7

Lysogenic infection

Answer 7

The genetic material of a virus is replicated along with the bacterial chromosome but the cell is not immediately destroyed

Question 8

Prophage

Answer 8

The DNA of a lysogenic bacteriophage that is inserted into the host chromosome

Question 9

Latent infection

Answer 9

Viral genetic information is inside the cell but not expressed. As long as the infection remains latent, new viruses aren’t produced

Question 10

Vaccine

Answer 10

Teaches the immune system to recognize one of more molecular components of a virus without actually exposing the person to the disease

Question 11

Viroid

Answer 11

A Highly wound circle of rna that lacks a protein coat

Question 12

Prion

Answer 12

Proteinaceous infectious particle. A normal membrane protein that can exist in multiple three dimensional shapes

Question 13

Virus

Answer 13
