Pick TWO of the FOUR mechanisms of spread of antibiotic resistance (spontaneous mutation, transformation, transduction or conjugation). For each: Antibiotic resistance mechanism 1: Clearly describe the meaning of the term in relation to antibiotic resistance (2 points) Indicate whether this is a method of vertical or horizontal gene transfer (1 points) Antibiotic resistance mechanism 2: Clearly describe the meaning of the term in relation to antibiotic resistance (2 points) Indicate whether this is a method of vertical or horizontal gene transfer (1 points)  

What causes ADH to be released?

A bacterial polycistronic operon with three (3) genes would have how many of the following?   A) PROMOTERS  __________ B) ACTIVATOR BINDING SITES  __________ C) OPERATORS  __________ D) TERMINATORS __________ E) PROTEIN PRODUCTS __________  

ANTIMICROBIALS and ANTIMICROBIAL RESISTANCE

Some pathogens make fimbriae to attach to cells lining the gut of their host. However, it would be a waste of resources to make fimbriae when not in the gut. In some bacteria, fimbrial gene transcription is initiated when the cell detects leucine, which would likely be abundant in a nutrient‐rich environment like a gut. The fimbriae (fim) genes are under positive control, wherein a regulatory protein (FRP) binds to an activator‐binding site when leucine is present In which scenario does transcription occur?

On a prescription, the abbreviation q.i.d means

Which of the following is the most appropriate indication for the application of dental sealants?

Which of the following actions should be take first in managing an office emergency?

A bacterial toxin was found to cause fever, vomiting, and diarrhea.  Upon structural elucidation this toxin was found to be a single-subunit protein that leads to a massive increase in cytokines, which results in toxic shock syndrome. Fever is a:
