DNA is the common name for Deoxyribonucleic acid. This is made up of nucleic acids containing deoxyribose (sugar)‚ consisting of complex molecules‚ present in the chromosomes of all plant and animal cells‚ and carrying in coded form instructions for passing on hereditary characteristics. The DNA molecule takes the shape of a double helix‚ a simple structure that resembles gently twisted ladders. The rails of the ladder are made of pairs of nitrogen-containing nucleotides‚ which are subdivisions

The DNA double helix model In 1953 James Watson and Francis Crick made a scientific breakthrough when they discovered the structure of DNA. From this structure they inferred that DNA contains information written in a genetic code‚ is passed from one generation to the next. This discovery was to be a key step in the genetics revolution DNA has four molecular building blocks called nucleotides; adenine (A)‚ thymine (T) guanine (G) and cytosine (C).
