Penicillin inhibits bacterial multiplication by: Checking spindle formation Destroys chromatin Inhibits cell wall formation Checking RNA synthesisDo explain your answer.

Penicillin inhibits bacterial multiplication by checking RNA synthesis.

 

Hence option D is correct.

Dear student 

Penicillin kills bacteria through binding of the beta-lactam ring to DD-transpeptidase, inhibiting its cross-linking activity and preventing new cell wall formation.In this sequence, Escherichia coli were incubated in penicillin for 30 minutes. The bacteria lengthen, but cannot divide. Eventually the weak cell wall ruptures.
