What is DNA? To give a simple answer, it is the molecule of life. DNA, or deoxyribonucleic acid, determines our physical characteristics - what we look like, our ailments etc. Many also believe that DNA is partly responsible for our behaviour. DNA exists in every single organism, from the smallest virus to the largest mammal. DNA is passed on from generation to generation.

Why is this molecule so fascinating you ask? Well, besides the fact that it is present in like EVERY organism and not to mention the attractive curves on its double-helical structure, it is the only known molecule that has ability to replicate itself. DNA is like a biological blueprint, which contains the instructions for proteins, an essential type of molecule of life.

This homepage examines the structure of DNA and DNA-related molecules that are involved, the processes of replication, and protein synthesis. Here you will also find a glossary of terms for quick and easy reference.
