Flashcards in Viruses Deck (11):
1

Capsid

protein coat of virus

2

Obligate parisites

cannot reproduce without host cell. They REPLICATE instead.

3

Bacteriophage

virus that infects bacteria

4

bacterium

bacteria that is infected.

5

Attachment

virus attaches to host cell
matches up with receptor sites on cell
some are specific to specific cells

6

Entry

virus creates hole in bacterium
nucleic acid pushed through
protein coat stays outside but when virus enters, so does coat and it is digested

7

Synthesis

nucleic acid of host is made inactive
virus nucleic acid joins with cell organelles and produces viral nucleic acid and proteins and infects other cells

8

Assembly

new viruses made in bacterium

9

Release

Viral molecules are released when host cells burst.

10

Lysis

host cells bursting

11

Interferons

chemicals released by virus infected cells to protect healthy cells.
