Researchers are designing several experiments to test the ability of Salmonella bacteria to develop antibiotic resistance. A culture of Salmonella bacteria is exposed to the same concentrations (200 mg/L) of an antibiotic for four days. The table shows the number of isolated resistant bacteria over a four-day period. Which of the following statements best explains these results?
A - The bacteria were not affected by the antibiotic.
B - After being exposed to the antibiotic, the bacteria altered their DNA.
C - A new species of bacteria emerged after the antibiotics were introduced.
D - Random mutations led some bacteria to be resistant and, over time, they increased in the population.
25) Identify the most correct choice:
a) ribosomes are the membrane bound organelles responsible for making
proteins from RNAs.
b) In gene therapy, Agrobacterium is the bacteria that transfers genetic material
into the human cells that contain the mutated gene.
c) spectrophotometer analysis can be used to detect the concentration of the
dead cells in a solution only and not those that are living.
d) None of the above.

C.arrow_forwardExplain Avery-MacLeod-McCarty experiment (the 1940's) with capsule forming bacteria (smooth) and non-capsule forming bacteria (rough). What did this classic experiment demonstrate?Why would a rapidly growing bacterial cell be killed by an antibiotic that blocks DNA replication? Suppose the bacteria form a biofilm on a catheter in a patient. Why might the bacteria have become resistant to the antibiotic?arrow_forwardIdentify the single most correct answer: a) Ribosome is an organelle found in both prokaryotes and eukaryotes. Ob) During conjugation a naked DNA molecule found in the surroundings gets into bacteria. c) Spontaneous mutation cannot result in the production of an altered protein. Od) Gene transfer from one species of bacteria to another (donor to recipient) represents horizontal gene transfer.arrow_forward

There may be more than one correct statement. A) primers are required in both PCR and DNA replication B) PCR is done in a tube while DNA replication occurs inside our cells C) PCR and DNA replication both use a type of DNA ploymerase D) PCR will always copy the entire chromosomearrow_forwardSelect the true statements: A.) It is possible, through genetic engineering, to fuse a fluorescent molecule (example GFP) with a non-fluorescent protein to create a fluorescent fusion protein. B.) Proteins are created during gene transcription. C.) It is possible to observe a fluorescent protein immediately after the plasmid coding for this protein is introduced into a cell. D.) The plasma coding for a fluorescent protein is also fluorescent. E.) It is possible to obtain a different color fluorescent fusion protein by replacing the sequence coding for the fluorescent protein in the plasmid for a sequence coding for a fluorescent protein by a different color sequence.arrow_forward
