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.
The nucleotides found in a DNA are Adenine, Guanine, Thiamine and Cytosine and in an RNA it is Adenine, Guanine, Uracil and Cytosine. Adenine always pairs with Thiamine and Cytosine pairs with Guanine in a DNA. RNA is generally single stranded but in cases where it is double stranded the same rules apply but here Adenine pairs with Uracil. The A-T and A-U bond is double bonded whereas the G-C bond is single stranded..
