DNA
Deoxyribonucleic acid (DNA) is a very important molecule found in all living cells. It contains information used in everyday metabolism and growth and influences most of our characteristics.
Answerd by martin | November 03, 2010
DNA is often described as the blueprint of an organism. It enables various cells to develop and work together to form a fully functional body, and controls characteristics such as eye colour. How much DNA influences very complex features, such as intelligence, is not yet fully understood.
The information that DNA contains is passed from one generation to the next. There is much debate over how much of what we are like is due to inheritance and defined by our DNA, and how much is defined by the influence of the environment. This is sometimes referred to as the 'nature/nurture' debate.
