Part of the new Ladybird Expert series, Genetics is an accessible, authoritative and insightful introduction to the code that shapes the lives of all living things - DNA. Written by broadcaster and geneticist Adam Rutherford, Genetics breaks down the DNA code - an alphabet of four letters and twenty-one words - that has been passed down from cell to cell for four billion years. You'll learn how in the 150 years since DNA was first discovered, we are beginning to understand, and even radically rewrite, the code of life on Earth. Written by the leading lights and most outstanding communicators in their fields, the Ladybird Expert books provide clear, accessible and authoritative introductions to subjects drawn from science, history, and culture. For an adult readership, the Ladybird Expert series is produced in the same iconic small hardback format pioneered by the original Ladybirds. Each beautifully illustrated book features the first new illustrations produced in the original Ladybird style for nearly forty years.
