Question

Antibiotics that affect bacterial cells interfere with all of the following EXCEPT

• A.
  peptidoglycan synthesis
• B.
  protein synthesis
• C.
  DNA synthesis
• D.
  reverse transcriptase

Answer 1

The correct option is A

peptidoglycan synthesis
Antibiotics work by interfering with the bacterial cell wall to prevent growth and replication of the bacteria. Human cells do not have cell walls, but many types of bacteria do, and so antibiotics can target bacteria without harming human cells.

Peptidoglycan is an important component of bacterial cell walls and an excellent target for antibiotics.

Antibiotic-induced bacterial cell death is associated with the formation of double-stranded DNA breaks following treatment with DNA gyrase inhibitors, and also with the arrest of DNA-dependent RNA synthesis and RNA-dependent RNA synthesis.

So, the correct answer is "option a".
