M250 Final Exam Questions Fully
Solved.
bacterial species - Answer a collection of strands that share important traits and 70%
DNA/DNA genome hybridization with a type strand
type strain - Answer an arbitrarily selected bacterial strain that has all of the hallmark traits
of the species to which it belongs
numerical taxonomy - Answer compare organisms based on similar traits - what is closest to
"type strain"?
DNA/DNA hybridization - Answer compare organisms based on total genome similarity
>70 % = same species
16S rRNA sequencing (phylogenetics) - Answer compare organisms based on evolutionary
relatedness to identify close relatives... >97% similar = same genus
polyphasic approach - Answer naming by a combination of all approaches
1) molecular chronometer
2) numerical taxonomy
3) DNA/DNA hybridization
naming by disease - Answer named based on the disease they cause... but does not work for
all pathogens
subunit of polysaccharides? - Answer carbohydrates
subunit of nucleic acids? - Answer nucleotides
subunit of lipids? - Answer fatty acids
subunit of proteins? - Answer amino acids
polysaccharides - Answer polymers of carbohydrates...
carbohydrates are "hydrated carbon" aka "sugars"
