Adam Rutherford's excellent series, 'The Cell', is a brilliant resource for teachers of biology. The three part series is produced to a very high standard and expertly presented by the amiable Rutherford. 'The Cell' examines the history of human understanding of the workings of the cell, principally by focusing on key scientists and experiments in microscopy, genetics and the discovery of DNA. It's truly excellent! The video below forms part of episode three of the series, 'The Spark of Life' which examines the quest for creating artificial cells, recreating the conditions of the primordial soup and the advent of the age of genetic engineering. The series is not available for purchase on it's own but comes free with Michael Moseley's 'The Story of Science - available on Amazon here.
