Footage description: | Derek Smith introduces the programme. He has with him a model of a tobacco mosaic virus. Robert Edgar with electron micrograph and model of a T4 phage. He points out the component parts of the phage as he disassembles the model. Edgar goes on to explain how the T4 phage infects bacteria and the effect of this infection. A model and several electron micrographs illustrate points made. Derek Smith recaps the points covered so far. Robert Edgar discusses the experiments, complementation and recombination, by which 100 genes in the T4 phage were isolated and mapped. Derek Smith recaps. Edgar, with a genetic map of the T4 phage, continues his discussion. Derek Smith recaps and introduces the next topic. Robert Edgar, using electron micrographs and a genetic map of the T4 phage, explains how the functions of particular genes and sets of genes were determined. Derek Smith recaps. Robert Edgar explains the process by which the T4 phage is assembled from its component parts and gives details of the experiments which elucidated these mechanisms. He uses models and charts to illustrate his points. Derek Smith sums up. |
