MIP 300 (Exam #1) You are tasked with trying to create an antibiotic to treat a bacterium called Bacillus nonstudyus. You find a drug that inhibits tetrapeptide crosslinking, and you also find it can inhibit this bacterium from sporulating. Based on the fact that this drug inhibits tetrapeptide crosslink formation, what step in sporulation is most likely being inhibited by this drug? - correct answer Formation of the cortex You have isolated a cell that possesses the following: double-strand...

MIP 300 Exam I review (CSU) The Cortex - correct answer You develop a drug that inhibits the formation of peptide interridge. You find that it also is effective at stopping sporulation. What part of the spore would you propose this drug is inhibiting formation of? Archaea, Bacteria, Eukarya - correct answer You have isolated a cell that possess the following: 70S ribosomes, double-stranded DNA, and a cytoplasmic membrane composed of a phospholipid bilayer. From this information, into which d...

Lab 2: Techniques for Isolation of Pure Cultures Learning Objectives:  Isolate pure cultures from a mixed population of microorganisms using aseptic technique.  Learn the streak plate method VIDEO:  Making a streak Plate (Bio-Rad Laboratories) Introduction: Microorganisms exist in nature as mixed populations of different species. In order to study them and observe their characteristics it is first necessary to obtain pure cultures (a culture containing only one species of an o...
