MIMG 101 Test Questions and
Answers.
Hydrogenosomes - Answer anaerobic endosymbiont that makes ATP via fermentation
working distance - Answer distance between objective lens and specimen
Fluorochromes - Answer absorb light and emit visible fluorescent light; labeled probes used
to localize specific proteins
gram negative - Answer the group of bacteria that have a structurally complex cell wall and
contain less peptidoglycan; often more toxic; can be rinsed of color by alcohol
gram positive - Answer the group of bacteria that have a less complex cell wall contain more
peptidoglycan than the cell wall of gram-negative bacteria; usually less toxic; hold crystal violet
dye
Mycobacteria - Answer have a cell wall with lipids that prevent dyes from binding to cells
viroids - Answer small circular RNA molecules that infect plants
satellites - Answer composed of nucleic acid enclosed in a protein shell
prions - Answer infectious protein particles that do not have a genome
oligonucleotide signature sequences - Answer short conserved nucleotide sequences specific
for phylogenetically defined groups
refraction index - Answer A measure of how much an object slows light
Cocci - Answer spherical bacteria
vibrios - Answer comma shaped bacteria
sprilla - Answer rigid spiral bacteria
