10.1   NEW GENERATIONS


CONTEXT FOR THIS UNIT

Among the most exciting discoveries in science over the last 50 years has been the discovery of the structure of DNA and how it is passed from cell to cell and from generation to generation - how it stays the same and how it changes. An understanding of how DNA works has filled in the last pice of the jigsaw puzzle of evolution - how and why living things have changed and adapted to new environments.
