In brief: Nucleotide sequence

Dna is a long chain of 4 molecules called nucleotides.
The sequence of three in a row, codes for Amino Acids used to build enzymes and body parts. Other sequences turn the code on and off for certain segments. All of the codes are still not known and some information is transfered in other ways. All in all it is a remarkable bit of biology.
