Cells are the basic units of life, but within them are even smaller structures that act as the machinery that keeps us alive. This include the key molecules in cellular biology, deoxyribonucleic acid and ribonucleic acid--better known as DNA and RNA. These teammates have essential jobs and they work together to make life possible. DNA stores and transfers genetic information, while RNA codes for amino acids and acts as a messenger in the making of proteins. This enlightening book erases much of the mystique surrounding the science of genetics, thanks to thorough explanations of DNA and RNA at work within the body. Numerous diagrams help make this potentially difficult topic more accessible.
