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.
Thymine versus uracil. Our genetic information is stored in the form of DNA, using a four-letter alphabet. The four âlettersâ correspond to the four chemical bases that each building block of DNA â called a nucleotide â can have: adenine (A), thymine (T), cytosine (C) and guanine (G; see Figure 1).
