The formation of peptide cross-links between adjacent glycan chains in cell wall synthesis is called (A) Transglycosylation (B) Autoglycosylation (C) Autopeptidation (D) Transpeptidation

Answer: (D) Transpeptidation
Transpeptidation is the process of forming peptide cross-links between glycan chains in bacterial cell wall synthesis, crucial for cell wall integrity and strength. Transglycosylation involves the formation of glycan chains, while autopeptidation is not a standard term used in this context.
