Question

Using your knowledge of DNA recombination events to complete the following: Propose two ways in which antibiotic resistance may develop in a bacterium Describe how bacterial cells acquire the ability to produce toxins (Use the following terminology in your answer: recombination, DNA, horizontal gene transfer, conjugation, transformation, transduction, pilus, F factor, transposable elements, transposons, pathogenicity islands)

Answer 1

Answer:

A) Propose two ways in which antibiotic resistance may develop in a bacterium?

Antibiotic resistance may develop in a bacterium through A GENETIC MUTATION and BY REQUIRING RESISTANCE FROM ANOTHER BACTERIUM

B.) Describe how bacterial cells acquire the ability to produce toxins?

The virulent strains of bacteria as in Corynebacterium diphtheria, and Streptococcus pyogenes all manufacture toxins with weighty physiological impacts, unlike the nonvirulent strains which do not manufacture toxins. The toxins are generated by a bacteriophage gene that has been received by transduction.
