Unit 8-Microbiology (Word Wall Words)

Question 1

Capsid

Answer 1

Protein coat around genetic material

Question 2

Envelope

Answer 2

Protein outside of capsid

Question 3

Bacteriophage

Answer 3

Virus that can only attack bacteria/no nucleus cells

Question 4

Prophage

Answer 4

DNA that bacteriophages carry

Question 5

Lyse

Answer 5

Burst or rupture

Question 6

Lytic Cycle

Answer 6

1. Takes over host cell’s protein synthesis machinery to make copies of itself
2. Cell explodes and dies
3. Virus copies go off and infect other cells

(Fast)

Question 7

Virulent virus

Answer 7

Deadly

Ex) Ebola

Question 8

Lysogenic Cycle

Answer 8

• Virus weaves its genetic material into host cell’s chromosomes
• Viral genetic material only copies when one cell copies
• May eventually enter lytic cycle in months or years

Question 9

Pathogen

Answer 9

Disease causing agent

Question 10

Vector

Answer 10

Carries pathogen

Ex) mosquito and West Nile

Question 11

Attenuated Virus

Answer 11

Zaps virus it with radiation to weaken it

Question 12

Inactivated Virus

Answer 12

Chops virus it up into pieces

Question 13

Retrovirus

Answer 13

Copy DNA from their RNA

Ex) HIV

Question 14

Reverse Transcriptase

Answer 14

Inject RNA

Protein??

Question 15

Viroids

Answer 15

Particles of RNA that cause disease in plants

Affect potatoes, coconuts, oranges

Question 16

Prions

Answer 16

Particles of protein that cause disease in animals
Ex) CWD- Chronic Wasting Disease
Ex) Mad Cow
(BSE- bovine spongiform encephalopathy and its variant human form vCJD)
(Creutzfeldt- Jakob Disease)

Question 17
