The genetic code is a nearly universal language that encodes directions for cells. The language uses DNA nucleotides, arranged in codons of three, to store the blueprints for amino acid chains.
DNA is the 'blueprint' to create, maintain and then reproduce the species in which it is carried. The genetic code is the order of four bases adenine, cytosine, guanine and thymine. Usually these are converted into another molecule similar to DNA called messenger RNA by a process called transcription.The code is carried by the mRNA to the nucleus where it is then read and turned into protein chain in a process called translation. On the whole, then DNA carries the information to produce proteins.ll the proteins needed to control the activity of genes and DNA function are also carried in the DNA molecule itself. Apart from protein codes, a few genes are dedicated to the synthesis of various types of RNA molecules which are needed for protein synthesis.
