DNA is found in the chromosomes of the nucleus in a cell and it carries hereditary information. RNA is located in the cell but not in the nucleus. Just as proteins consist of long chains of amino acids, DNA and RNA consists of nucleic acid chains called nucleotides. Nucleotides are composed of three units: base, sugar (monosaccharide) and phosphate. Bases are found in both DNA and RNA. As seen below, they are adenine, cytosine, guanine, thymine, and uracil.
Table 1 shows the genetic code of the messenger ribonucleic acid (mRNA), i.e. it shows all 64 possible combinations of codons composed of three nucleotide bases (tri-nucleotide units) that specify amino acids during protein assembling.
