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.
Figure 4: Guanine and cytosine form a base pair stabilised by three hydrogen bonds, whereas adenine and thymine bind to each other through two hydrogen bonds. The red frames highlight the functional groups of cytosine and thymine that are responsible for forming the hydrogen bonds.ells have a repair system that can detect when a uracil is sitting where a cytosine should be, and correct the mistake before it is replicated and passed on. The complex machinery to do that consists of several enzymes: first uracil-DNA glycosylases recognise the uracil, and cut it out of the DNA.
