DNA is a natural polymer
DNA stands for deoxyribonucleic acid. It is a large molecule and a naturally occurring polymer found in living organisms and viruses. Most DNA molecules consist of two chains, each made from a sequence of discrete nucleotide units, although some DNA molecules are single-stranded.
Step-by-step lessons on AQA GCSE Chemistry 7.3.4 DNA (deoxyribonucleic acid) and other naturally occurring polymers. Each one builds up to exam-style questions. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
