Question

Identify an antibiotic from the following

• A. Chloramphenicol
• B. Ethephon
• C. Phosphon-D
• D. AMO-$1618$

Answer 1

The correct option is A Chloramphenicol

• Chloramphenicol is a semisynthetic antibiotic. It is derived from Streptomyces venequelae. It is a broad-spectrum antibiotic. It inhibits bacterial growth by binding reversibly to the bacterial 50S ribosomal subunit.
  
• Ethephon is a plant growth regulator. It is used in fruit ripening, abscission, etc.
  
• Phosphon-D is an inhibitor of gibberellin biosynthesis.
• AMO-1618 is a plant growth retardant. It is used as an inhibitor of squalene-2,3-oxide cyclase.
  

Thus, the correct answer is 'Chloramphenicol.'
