Description

How is genetic information stored in cells, and how is the information accessed and used? On this album, Dr Norman Cohen of The Open University uses models and graphics to provide easily understood explanations of how genetic information is stored in DNA, how DNA is replicated, and how genetic information from DNA is used to create new protein molecules. The album draws on material originally created to support The Open University course Exploring science.
