Question 4

The pathway where a virus lies dormant for a period of time within the cell before beginning its reproductive cycle

Answer 4

Lysogenic cycle

Question 5

The cycle of viral replication which causes the host cell to burst open (in a short time)

Answer 5

Lytic cycle

Question 6

Virus which no longer contains its genetic material

Answer 6

ghost

Question 7

Virus which attacks Bacteria

Answer 7

bacteriophage

Question 8

A host cell that has viral genetic material incorporated into its DNA

Answer 8

Prophage

Question 9

An injection given to produce immunity to a viral disease

Answer 9

Vaccine

Question 10

… cells allow the body to react faster to an infection if the body is exposed to the pathogen more than once

Answer 10

antibody

Question 11

a disease causing organism (could be virus or bacteria or parasite)

Answer 11

pathogen

Question 12

Viruses considered nonliving because they cannot … without the help of a host cell

Answer 12

reproduce

Question 13

A virus with RNA as its genetic material

Answer 13

retrovirus

Question 14

Compared to bacteria viruses are much … in size

Answer 14

Smaller

Question 15

Living characteristics of viruses

Answer 15

• reproduce but only in a host cell
• have DNA
• have a life cycle

Question 16

Nonliving characteristics of viruses

Answer 16

• cannot reproduce without a host
• are not made out of cells
• do not require a nervy
• do not produce waste
• do not metabolise food
• do not respond to their environment
• no cell membrane/ organelles/ cells
• do not have a limited life span

Question 17

Viral structure

Answer 17

Capsid/ protein coat
Nucleus acid/ genetic material (DNA)
Attachment fibers/ tail fibers

Question 18

Virus in Latin

Answer 18

Poison

Question 19

Vaccines inject …

Answer 19

Dead or weak virus

Question 20

Viral diseases with vaccine

Answer 20

Measles
Chicken pox
Flu
HPV
Hepatitis

Question 21

Viral diseases without vaccine

Answer 21

HIV
Herpes
Common cold

Question 22

Lytic cycle

Answer 22

Fast
No chance of deactivation
Virulent- kills host
Example- cold, flu, Ebola, influenza, small pox, chicken pox

Question 23

Lysogenic cycle

Answer 23

Long time/ slow
DNA remains in host cell (Prophage)
Chances of reactivating
temperate- long time to make sick
Examples- HIV, shingles, herpes

Question 24

Virus like that infect and cause disease in plants. Single stranded RNA but no capsid

Answer 24

Viroids

Question 25

Virus like which infects and causes disease in animals | No DNA or RNA only protein

Answer 25

Prions
