DNA and the genome

  • 1 The chemical structure of DNA Resource
  • This unit explores the chemical nature of the genome. Genomes are composed of DNA, and a knowledge of the structure of DNA is essential to understand how it can function as hereditary material. DNA is...
  • 2 How DNA is replicated Resource
  • Cell division involving the nuclear division of mitosis produces two progeny cells, which contain identical genetic material, which is also identical with that of the original parent cell. This is how...
  • 3 Chromosome structure and DNA replication Resource
  • DNA replication is closely linked to chromosome replication, which in turn is linked to cell division, which includes the nuclear division of mitosis. This raises an intriguing question: how many DNA molecules...
