QUESTION 35 Tetracycline is an antibiotic used to treat bacterial infections in humans because it prevents the growth and spread of bacteria. This drug is known to bind strongly and specifically to the A site in the 30S ribosomal subunit. Based on this information you would expect that: a. tetracycline does not affect translation in eukaryotic cells. b. tetracycline inhibits RNA splicing in prokarytes. c. tetracycline will prevent the small ribosomal subunit from binding to the Shine-Dalgarno sequence. d. tetracycline...
Molecular formula of amoxicillin (antibiotic used to treat bacterial infections) is C16H19N3O5 How many hydrogen atoms are in 5.00 mL (density = 1.54 g/mL) of amoxicillin?
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....
Zithromycin inhibits protein synthesis in bacteria. However, it cannot cross gram-negative bacteria cell walls. Would you expect zithromycin to be broad or narrow spectrum? Why? Amphotericin B disrupts the plasma membrane by binding to sterols. Why can’t it be used to treat bacterial infections? Match the following processes with the statements listed below. (Answers may be used more than once.) a. transcription b. translation c. DNA replication Ciprofloxacin inhibits DNA helicase. Which process is inhibited? _______________ RCT is a nucleotide substitute for uracil. Which process is inhibited? ___________ Tetracycline...
