When examining the basic components of DNA, the mole percentage of guanine is comparable to cytosine and the mole percentage of adenine is according to thymine [3]. DNA and RNA have five major bases namely Adenine, Guanine, Thymine, Cytosine, and Uracil. flashcard sets. A fifth nucleotide, uracil, replaces thymine in RNA. On the other hand, another cell might read a different recipe, which tells it how to make insulin protein to control blood sugar levels. Molecules as complex as RNA must have arisen from small molecules whose reactivity was governed by physico-chemical processes. of ssRNA (e.g., RNA Transcript): M.W. C will only bond with G and A will only bond with T in DNA. This is one of 4 kinds of units for constructing a multi-unit model of a molecule of deoxyribonucleic acid in double helix configuration: a stack of about 15 units will illustrate the principle, but the actual molecules contain about 12,900 such units if we accept a molecular weight of 8 million.
