Biology KS3/4: Global warming resistant GM crops

Brian Cox meets a plant scientist who describes the benefits of genetic modification of plants. Brian then describes the history of the discovery of DNA in Cambridge by Crick and Watson.

He discusses the work of Rosalind Franklin, explains the significance of Photograph 51 and outlines how this allowed her to suggest the double helix structure, leading to Crick and Watson being able to build their famous model.

He describes the significance of genetic sequencing and how this has ultimately led to the controversy around genetic modification.

Teacher Notes

This could be used to launch discussions on selective breeding and genetic modification. Students can discuss some other ways in which man's scientific activity impacts on the environment. Encourage students to consider other controversies in science and debate on the pros and cons of scientific progress.
