About DNA - The Double Helix

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.

DNA - The Double Helix Game

- 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.

About the educational games

The educational games are based on Nobel Prize awarded discoveries and were produced between 2001 and 2012. The games have not been updated since production (including potential scientific facts changes) and are provided here on an 'as is' basis by popular demand.

The games require Adobe Flash Player. Adobe Flash is an old technology with an end of life by 2020 and these games will then no longer work. Flash is disabled in many browsers and need to be activated in order to play the games.
