Cracking the genetic code

Codes are used for all sorts of things such as sending secret messages (for example the enigma code), converting messages into light (for example the code used by lighthouses so that they could be identified),  and for sending messages by telegraph (Morse code, developed by Samuel Morse in 1836.

There is one code that is universal, and which makes us human. This is the code of DNA , whose structure was described by James Watson and Francis Crick, using the data produced by Rosalind Franklin and Maurice Wilkins. Many scientists have since worked to elucidate the genetic code, and work is still on going. In 1990, the human genome project was launched, to discover the sequence of a human’s DNA, and to identify all the genes. This project too approximately 13 years!

Saturday Science Club this week will be looking at how the genetic code works, what it can tell us, and even what it looks like!
