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.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_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_forward
- Genetic information can be transferred horizontally from one bacterial cell to another cell of the "same generation" (versus daughter cells), leading to genetic recombination, by all of the following EXCEPT: A. Gene expression (transcription/translation/protein synthesis) B. Transformation C. Conjugation D. Transduction E. None of the other four answers (all are mechanisms of “horizontal transfer” genetic recombination)arrow_forwardChoose the statements below which are correct. 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

In this situation, it can be said that: (a) certainly the process in question was being conducted in anaerobiosis (B).Acetate accumulation is advantageous for the process as the acetate formation reaction generates 1 molecule of ATP (c)Knowing that decreasing the temperature of the process causes a reduction in the rate of glycolysis, this could be a strategy to reduce the accumulation of acetate (d).the acetate formed can be re-assimilated by the cell if the glyoxylate pathway is activated at some point in the culturearrow_forwardPlease answer all of these questions in details Answer all of the following questions a) Define the following terms: biotechnology, Plasmid,Genetic engineering and Transformation b) List two types of medical products that can be produced using DNA tech- nology c) Relate bioethics to the continued development of genetic engineering techniques. d) Describe two major goals of the Human Genome Project. e) Distinguish between proteomics and genomics. f) Outline the different applications of biotechnology g) List some techniques of genetic engineering. h) Delineate the transgenic organisms and their significance. i) Explain the procedure for the following PCR, Gel electrophpresis and Gene therapy j) Describe human genome project and its main goals. k) Discuss the drastic environmental impacts of oil spills and how the mi- crobes like bacteria can help mitigate the problem. l) Give an account of significance of transgenic organisms in food industry. m) Describe the uses of DNA finger…arrow_forward
