Why are bacteria an excellent tool for genetic research? -Grow extremely quickly -Very easy to isolate one species or strain of bacteria, typically through the selection of antibiotic-resistant strains -Bacteria can be grown in almost any laboratory, typically with little risk, and their source of nourishment is extremely inexpensive 2. Spontaneous mutation Refers to the process by which bacteria undergo random mutations, some of which may be advantageous to survival in an otherwise h...

What microbes can degrade and/or utilize every molecule on earth? Correct Answer-bacteria and archaea What is botulism used for? Correct Answer-medicine (is a very potent toxin; is a paralytic) How do we identify new bacteria? Correct Answer-by sequence analysis of universal genes (i.e. with rRNA) What is a process that is preserved between cells? Why? Correct Answer-translation of ribosomes; it is a complex process with lots of restraints on mutations (i.e. genes mutate very slowly) ...

Hershey and Chase performed an experiment in order to determine how bacteriophages infect bacteria. What did they find? CORRECT ANSWER The bacteriophage injects DNA into the host cell. This was found because, after centrifugation, the pellet was radioactive The largest difference between a Gram + and Gram - bacterial cell is: CORRECT ANSWER The gram + cell has a much thicker peptidoglycan layer Why does a Gram + cell stain blue/purple in a gram stain? CORRECT ANSWER The Gram + cell stains ...
