BACTERIA 3

Question 1

diseases viruses cause

Answer 1

colds, AIDS, warts, mesales, mumps, HPV, polio, chicken pox, small pox

Question 2

virusues

Answer 2

attached to cells, not cellular, need host cell, intravellular paraistes

Question 3

structures of viruses

Answer 3

protein coast: capsid, intercore of nucleic acid (DNA or RNA), envelope

Question 4

capside

Answer 4

protein coat, made of nucleic acid

Question 5

envelope

Answer 5

made up of membrane from host cell

Question 6

bacteria phage

Answer 6

viruses that infect bactiera, typical: attach to host cell, then inject nucleic acid in, take over cell’s metabolism, direct host’s cell metabolism to creat enew virus particesl inside of host cell using part os host

Question 7

lysis

Answer 7

cel membrne breaks and it spreads

Question 8

state of lysogeny

Answer 8

k

Question 9

lytic cycel

Answer 9

reproductice cycel, result in lysis of host cell and release virus that were produce within the cell,

Question 10

lysogenic cycle

Answer 10

virual DNA replication occurs without destroying host cell 1. dna inserrted by genetic recombination into bacterial chromsome, phage DNA is referred to as a prophase and most of it genes are inactive, viral DNA integrate into host DNA, when segreate create daughter cells

Question 11

lytic cycle

Answer 11

1. enter bacterium 2. form circle 3. dna immediately turns cell into virus producing factor 4. cell soon lyses and release viral products

Question 12

porphage

Answer 12

once virus inserted, phage DNA

Question 13

new virus particles

Answer 13

two strands of rNA and proteins, bud through membrane and take membrane with it, result : killing cell

Question 14

retrovirus

Answer 14

examples : HIV (human), FIV (feline), SIV (primates)

Question 15

T lymopcyle

Answer 15

white cell, important for immune response, kill these: immune system is crippled

Question 16

HIV

Answer 16

has envelope and capusule, inside two strands of RNA, three enzymes

Question 17

three enzymes

Answer 17

reverse trasncriptase protease, integrase

Question 18

reverse trasncription

Answer 18

RNA to DNA, done by reverse trasncriiptase

Question 19

HIV story

Answer 19

1. merging of membrane 2. uncoasting : capside break up and release RNA and enzyme 3. reverse trasncription: make one side RNA, result = piece of nucleic acid, 1/2 DNA 1/2 RNA (that is used to make single stranded DNA

Question 20

HIV story 2

Answer 20

4. tkae off RNAm result DNA 5. replciated to double DNA (viral) 6. go into nucleus, integratse assist with integration, then can be in a dormant stage, when it become active it starts getting transcribed into nucleus and makes viral RNA 7. viral RNA get out of nucleus to the ribosome 9. make capsid proteins RESULT= virus particle gets out of cell,

Question 21

integration

Answer 21

integrase into host genome, done by integrrase

Question 22

protease

Answer 22

needed to make virus particles (reverse transripctuase, integrase, protease, and capside proteins), chopps polypepetide chain into all protines
