Q.4 Antibiotic resistance marker that CANNOT be used in a cloning vector in Gram negative bacteria is
(A) Streptomycin
(B) Ampicillin
(C) Vancomycin
(D) Kanamycin
Answer
Answer: (C) Vancomycin
Vancomycin is not typically used as an antibiotic resistance marker in cloning vectors for Gram-negative bacteria. Ampicillin, kanamycin, and streptomycin are commonly used for this purpose, but vancomycin is more relevant to Gram-positive bacteria.
