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.

Vaccination
Vaccinations are now considered a part of everyday life, but how do they work? Vaccination is a free course that will help those with a background in biology understand the historical development of vaccination, ------ the various types of vaccines used today, examine their production and explore the limitations that are placed on vaccination programmes.

Meiosis and mitosis
This free course, Meiosis and mitosis, looks at how units of inheritance are transmitted from one generation to the next. First you will look at what happens to the chromosomes of animals and plants during the process of sexual reproduction. Then you will examine how genes are transmitted in particular patterns from generation to generation. These two approaches combine to illustrate how the patterns of inheritance can be explained by the behaviour of chromosomes during sexual reproduction.
