Cracking the Code


We have produced a Style Guide to help editors follow a standard format when editing a listing. If you are unsure how best to edit this programme please take a moment to read it.
In 1990, 4-year-old
Ashi De Silva became the first person to be treated for a fatal disease with gene therapy. Such treatment is still rare, but the fact that many of the genes responsible for inherited diseases, such as cystic fibrosis, have been located, means that test-tube eggs which carry them can be discarded, and only healthy eggs returned to the body.
Thus the Ashe family know that their second child will not have to suffer as their first has.
But such breakthroughs have repercussions. Not only health, but also looks and intelligence could be influenced by genetic engineering. Once we start re-designing our children where will we stop?
"The line dividing those who should be changed and those who could be changed will be very hard to fix, " says David Suzuki in the fifth part of this series which look at the human stories behind the latest DNA discoveries.

About this project

This site contains the BBC listings information which the BBC printed in Radio Times between 1923 and 2009. You can search the site for BBC programmes, people, dates and Radio Times editions.

We hope it helps you find information about that long forgotten BBC programme, research a particular person or browse your own involvement with the BBC.

Through the listings, you will also be able to use the Genome search function to find thousands of radio and TV programmes that are already available to view or listen to on the BBC website.

There are more than 5 million programme listings in Genome. This is a historical record of the planned output and the BBC services of any given time. It should be viewed in this context and with the understanding that it reflects the attitudes and standards of its time - not those of today.
