BACTERIA 2

Question 1

how bacteria preoduce

Answer 1

binary fission

Question 2

binary fission

Answer 2

single form of cell dividon, no complex, singular loop of DNA replica

Question 3

F factor

Answer 3

carries genes for making sex pili and other reqirements for conjugation, contains origin of replication where DNA replcation can start

Question 4

conjugation

Answer 4

sexual exchange

Question 5

plasmid

Answer 5

small circular DNA molecule sepearte from bacterial chromosomes, has origin of replication,

Question 6

when one plus strane and negative strane get together

Answer 6

replication F factor and transger one whole copy

Question 7

plus

Answer 7

male

Question 8

negative

Answer 8

female

Question 9

R sex pilus

Answer 9

throw out hook and pull in strane, form conjucation tube and then sex factor goes to other one and become positive, male

Question 10

having sex factor

Answer 10

allows them to have sex philius

Question 11

transofration

Answer 11

when bacteria changes phoenytpe, result of conjugation

Question 12

sporuatlion

Answer 12

when bacteria created thick resistant coasting, become endospore, when conditions become unfavorable

Question 13

endospore

Answer 13

resistant to everting but insineration, when boiling, killing almost eveything but some can resist

Question 14

nitrogen fixation

Answer 14

converting automspheric nitrogen into amonia,
done by nitrogen fixing bacteria

N2 —> NH4+1

Question 15

amonia

Answer 15

can then be turned into nitrate and nitrite , done by nitrifying bacteria, process: amonium nitrification

Question 16

nitrate (NO3-1)

Answer 16

can be used by plants in metabolism used by plants to make nitrogen containing compound

Question 17

nitrogen containing compound

Answer 17

can be used to make nitrogen bases (DNA, RNA) and amino acids

Question 18

R plasmid

Answer 18

genes for antibiotic resistance

Question 19

rod

Answer 19

bascillus, common, tetrus, temerpulos, ecoli, nemonia, occur ingly but cell of some psecies occur in pairs (diplobacilli) and in chains (streptobacilli
