bio 260 test 1 (chapter 1-3) UPDATED ACTUAL Questions and
CORRECT Answers
microbiology The study of microorganisms; more than 50% of the world
have circular chromosomes (prokaryotes or eukaryotes) prokaryotes
lack membrane bound organelles (prokaryotes or prokaryotes
eukaryotes)
, cell division, binary fission, asexual (prokaryotes or prokaryotes
eukaryotes)
sexual+asexual reproduction (prokaryotes or eukaryotes) eukaryotes
multiple chromosomes (prokaryotes or eukaryotes) eukaryotes
linear DNA (prokaryotes or eukaryotes) eukaryotes
bigger, multicellular (prokaryotes or eukaryotes) eukaryotes
smaller, unicellular (prokaryotes or eukaryotes) prokaryotes
one chromosome (prokaryotes or eukaryotes) prokaryotes
type of cells (prokaryotes or eukaryotes) both
DNA (prokaryotes or eukaryotes) both
ribosomes (prokaryotes or eukaryotes) both
endosymbiotic theory mitochondria/chloroplast were both ones prokaryotes. They have similar
ribosomes, circular chromosomes, size, and two membranes.
pathogens microbes that cause diseases
opportunistic pathogens cause disease only in weekend host; very common
archaea don't care about them because they don't harm us. we don't really know what they
do
strain recognize genetic variants of the same species (caused genetic differences)
Binomial nomenclature system two name system (Genus is the first name; species is the second)
symbiotic relationship two organisms are closely connected different relationship
parasitism hurt the host
mutualism help the host, both benefit
commensalism no benefit or cost to the host
morphology shape
monomorphic bacteria that has one shape
pleomorphic bacteria can take on different forms
