DNA is a polymer with a double helix structure that carries genetic information.

Polypeptides are condensation polymers formed from amino acids. They contain peptide bonds.

Proteins are polymer molecules made from joining amino acids together. They contain one or more polypeptide chains.

Nucleotides are monomers that join together to make the polymer chains in DNA.

Amino acids are monomers that join together to form polypeptides and proteins.

In the Chemistry of Carbon unit, pupils learned about the structure and bonding of carbon, and its ability to form various compounds.

This unit covers identifying functional groups, naming and drawing structural formulae, and predicting reactions of alkanes, alkenes, alcohols, and carboxylic acids. It explains addition and condensation polymerisation and discusses natural polymers like DNA, sugars, and amino acids.
