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.
Uracil is composed of four hydrogen, four carbon, two nitrogen, and two oxygen atoms that are bonded together. This bonding pattern gives uracil a distinctive ring shape. It enables uracil to bond freely with adenine during base pairing.
