Q

Syringe

A

virus injects nucleic acid through cell membrane (bacteriophage)

17
Q

Engulfment

A

virus taken into cell whole,capsid is degraded and releases it’s DNA (Naked Virus)

18
Q

Fusion

A

viral envelope fuses with host cell membrane,capsid is taken into cell,is degraded and then releases it’s DNA (Envelope Virus)

19
Q

Penetration

A

virus gets its nucleic acid into host cell cytoplasm

20
Q

Biosynthesis

A

viral DNA,takes over the host cell machinery(pathways,enzymes,transcription and translation)

21
Q

Assembly

A

viral parts put together to make new virus

22
Q

Maturation

A

millions of new viruses are made each cycle

23
Q

Release

A

virus instructs host cell to bursts

24
Q

Lysogenic Cycle

A

attachment penetration, viral DNA is incorporated into the host cell chromosome, and viral genes goes dormant until triggered

25
Q

Environmental Trigger

A

environmet triggers activity of the virus

26
Q

Hanta Virus

A

is a virus that comes from mice,and it causes the air sacs in human lungs to fill with plasma membrane

27
Q

Deer Mouse

A

spread the virus
