It was discovered in 1953 by two scientists, James Watson and Francis Crick. They believed that their discovery would change the future of medical research. Tell me more DNA is organised into sections called genes. Every cell in the body contains all the genetic information of an individual's physical characteristics. Genes are inherited.
Scientists are now able to study single genes.
It has taken scientists twenty-five years to find out how to manipulate DNA in order to affect health. The discovery of DNA has enabled scientists to test for genetic disorders and repair them. A new treatment, called Genetic Engineering, has come about because we now understand the fundamentals of our genetic make-up.
