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.
Remember that the sugar for DNA is deoxyribose, and that for RNA is ribose. The nitrogenous bases adenine, guanine, and cytosine in DNA and RNA are the same. However, DNA which contains thymine and RNA that contains uracil. The structure of DNA is a double helix. There are three different structures of RNA: linear, clover-leaf, and globular.
