The bactericidal antibiotic penicillin kills bacterial cells by preventing peptidoglycan (cell wall) biosynthesis. Which of the following phases of the bacterial growth curve would you expect penicillin to be most active against?
Penicillin is an enzyme-inhibiting antibiotic that kills bacteria by suppressing the synthesis of bacterial cell walls....
Penicillin is an enzyme-inhibiting antibiotic that kills bacteria by suppressing the synthesis of bacterial cell walls. The bacterial cell wall is made of cross-linked peptidoglycan, which is synthesized from peptidoglycan monomers by transpeptidase enzymes. How does penicillin suppress the synthesis of bacterial cell walls? O Penicillin binds to the cross-linked peptidoglycan, preventing further bacterial cell wall growth. Penicillin signals the bacterial cell to stop producing the transpeptidase enzymes. Penicillin binds to the transpeptidase enzymes, preventing the synthesis of cross-linked peptidoglycan....

Neisseria has acquired resistance to penicillin. How can it achieve this? A) Neisseria bacteria are dormant and penicillin works on active cells B) Neisseria bacteria are too small for penicillin to kill C) Neisseria bacteria are constantly changing for penicillin to work D) Neisseria bacteria produces proteins to make penicillin ineffective
Which statement about gene cloning is false? A. Bacterial cells take up recombinant plasmids by transformation....
Which statement about gene cloning is false? A. Bacterial cells take up recombinant plasmids by transformation. B. Recombinant DNA molecules usually contain a DNA fragment inserted into a bacterial vector. C. To insert a gene of interest into a vector, the gene of interest and the vector must be digested with different restriction enzymes D. Transformed bacteria are plated onto media containing the appropriate antibiotic and only bacteria containing the plasmid with antibiotic resistance will grow.
