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.
3) As well as the nitrogen bases found in DNA, A (adenine), G (guanine), and C (cytosine), RNA nucleotides also have U (uracil) instead of T (thymine). U (uracil) is also complementary to A (adenine) when RNA base-pairs with another nucleic acid.
