BACTERIA 2 Flashcards
how bacteria preoduce
binary fission
binary fission
single form of cell dividon, no complex, singular loop of DNA replica
F factor
carries genes for making sex pili and other reqirements for conjugation, contains origin of replication where DNA replcation can start
conjugation
sexual exchange
plasmid
small circular DNA molecule sepearte from bacterial chromosomes, has origin of replication,
when one plus strane and negative strane get together
replication F factor and transger one whole copy
plus
male
negative
female
R sex pilus
throw out hook and pull in strane, form conjucation tube and then sex factor goes to other one and become positive, male
having sex factor
allows them to have sex philius
transofration
when bacteria changes phoenytpe, result of conjugation
sporuatlion
when bacteria created thick resistant coasting, become endospore, when conditions become unfavorable
endospore
resistant to everting but insineration, when boiling, killing almost eveything but some can resist
nitrogen fixation
converting automspheric nitrogen into amonia,
done by nitrogen fixing bacteria
N2 —> NH4+1
amonia
can then be turned into nitrate and nitrite , done by nitrifying bacteria, process: amonium nitrification
nitrate (NO3-1)
can be used by plants in metabolism used by plants to make nitrogen containing compound
nitrogen containing compound
can be used to make nitrogen bases (DNA, RNA) and amino acids
R plasmid
genes for antibiotic resistance
rod
bascillus, common, tetrus, temerpulos, ecoli, nemonia, occur ingly but cell of some psecies occur in pairs (diplobacilli) and in chains (streptobacilli
cocus
sphere shaped, streptococuss, staphylococci, strepococci
spillrium
bacteria cause lyme disease, casued by ticks, syphrillus, cork screw shaped, helical, relatively short and rigid
vibrio
comma shaped
streptococcus
causes strep throat, cocci
streptococci:
occur in chains, cocci
staphylococci
occur in clusters, cocci
spirochetes
long, flexible,
