Four letters make up the DNA of life on Earth and naturally stores its information in just four key chemicals - guanine, cytosine, adenine and thymine, commonly referred to as G, C, A and T. GENES: Cells contain a recipe manual for making proteins - we know this as Deoxyribonucleic acid (DNA). Cells were discovered by Robert Hooke who noticed moving cells in water through a microscope (I think) and we now know that cells make up all life forms on this planet (plants, fungi and animals - including man). All cells look quite similar and contain mitochondria (which is similar to an amazing battery that gives our cells energy). THE CELL is the basic function of all life. He wondered how it can be different but still have and be full of purpose.
Nurse was first inspired to look at this subject by observing a butterfly in his garden. The book looks at five different areas the cell, genes, life as chemistry, life as information and evolution by natural selection. This short and fascinating book looks at how and what life is. Wonderful and thought provoking short book on life
