Most DNA molecules are two polymer chains, made from four different monomers called nucleotides, in the form of a double helix.

Most DNA molecules are two polymer chains, made from four different monomers called nucleotides, in the form of a double helix. This objective belongs to Polymerisation and naturally occurring polymers within Reactions of alkenes and alcohols (chemistry only) for AQA GCSE Chemistry 8462. A strong answer should use DNA accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
