what does DNA ultimately code for
Superimpose code. The genetic code by which DNA stores the genetic information consists of codons of three nucleotides. The functional segments of DNA which code for the transfer of genetic information are called genes.With four possible bases, the three nucleotides can give 4 3 = 64 different possibilities, and these combinations are used to specify the 20 different amino acids used by living organisms.ore specifically, the sequence of bases bonded to the sugar phosphate backbone of the double helix contains information in the form of three-base codons that specify the sequence of amino acids to be used in the construction of proteins.
