E) nucleases; nucleotides

Peptidases

Proteins that catalyze the conversion of peptides to amino acids by cutting the bonds linking amino acids together.

Proteins

Large, complex molecules that play many critical roles in the body, including catalyzing metabolic reactions, DNA replication, and transporting molecules.

Nucleases

Enzymes that break down nucleic acids by cleaving the phosphodiester bonds between nucleotides.
