Bla is a gene, which is incorrect for it?

A. It is an antibiotic resistance gene

B. Antibiotic acts by blocking the cross-linking of the bacterial cell wall and thus leading to lysing of cells

C. It encodes beta-lactamase enzyme

D. The beta-lactam ring is activated

Explanation: Bla is an ampicillin resistant gene. Antibiotic acts by blocking the cross-linking in the bacterial cell wall and thus leading to lysing of the cells. If antibiotic resistant gene is used, which encodes for beta lactamase enzyme it inactivates the beta lactam gene by hydrolysing it.
