quiz 2
| Question | Answer |
|---|---|
| deuteromycetes | asexual reproduction only |
| zygomycetes | aseptate, produces spores via sporangium |
| sporangium | sac like structure full of spores, used in Zygomycetes for reproduction |
| ames test | test for mutation or cancer |
| coagulase test | test for staphareus/ will see clumping |

| monomorphic yease | always a yeast never a mold |
| pseudomycelium | yeast that produces projections but are false filaments |
| induced mutation | mutation caused by outside factor |
| bacteriophage | contains DNA for transduction |
| transformation | DNA transferred as "naked DNA" and inhibits recombination |
| transduction | DNA transferred via bacteriophage |

| resistant enzyme | "cuts" one sequence of DNA; "sticky ends" basse paring |
| Auxotroph | requires growth factor |
| prototroph | no growth factor required |
| alpha hemolysis | partial lysis of RBC |
| beta hemolysis | complete lysis of RBC |
