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.   In DNA, the matching base pairs are:   Adenine-Thymine   Guanine-Cytosine   In RNA, uracil takes the place of thymine.   uracil. In RNA, there are four kinds of base: adenine, guanine, cytosine and uracil. No, adenine bonds with thymine in Dna, while adenine bonds with uracil in Rna [the pairs AT & AU].
