- Ribozyme is class of molecule that is made of RNAs (thus "ribo" in its name) and amino acids (thus "zyme" in its name). True FalsePeptidoglycan (PG) is a heteropolymer that consists of glycan strands cross-linked by short peptide fragments and makes up the cell wall of archae . True FalseDefine peptidase
- Penicillin is an antibiotic. It kills bacteria by preventing the formation of the peptidoglycan layer of the bacterial cell wall.
