The DNA - The Double Helix educational game and related reading are based on the 1962 Nobel Prize in Physiology or Medicine, which was awarded for the discovery of the molecular structure of DNA – the double helix.
- How is a DNA molecule built up?
- How are copies of a DNA molecule made?
- What does "base-pairing" mean?
- How does the genetic material in thale cress (a plant), house mice, human beings, Escherichia coli bacteria, tuberculosis bacteria, bakers' yeast, malaria mosquitos and malaria parasites differ?
DNA (deoxyribonucleic acid) is the genetic material in all known living organisms and some viruses. DNA contains two strands wrapped around each other in a helix, and these strands are held in place by four chemicals called bases: adenine (A), guanine (G), cytosine (C) and thymine (T). The bases pair up with each other in a specific manner to form units called base pairs - adenine always pairs with thymine, and cytosine always pairs with guanine.
In this game your job is to first make exact copies of a double-stranded DNA molecule by correctly matching base pairs to each strand, and to then determine which organism the DNA belongs to.
