In nucleic acids, the bases which carry information are able to stick together because of hydrogen bonds. Cytosine sticks to guanine with three hydrogen bonds, and thymine can stick to adenine with two bonds.
In these diagrams the line shows where the base is joined to the sugar of the backbone of the nucleic acid. This sticking is very important in life. To help us understand why, first lets try to simplify these complex diagrams a little. |
