The color wheel is made up of three different types of colors - Primary, Secondary, and Tertiary. The primary colors are red, yellow, and blue. They are called primary for a couple of reasons. First, no two colors can be mixed to create a primary color.
RNA contains uracil and DNA Thymine. RNA has five bases, but DNA only four. DNA contains a deoxyribose sugar, but RNA contains ribose sugar. DNA is a double strand of nucleotides, but RNA a single strand.
Cytosine, guanine and adenine are found in both RNA and DNA molecules, while thymine is only in DNA and uracil is only in RNA. All five of the bases have a complex ring structure made up of carbon and nitrogen atoms. Due to the nitrogen atoms found in the ring, the bases are also referred to as nitrogenous bases.
