Step 11: A little about DNA
For people who don't know all that much about DNA:
DNA stands for Deoxyribonucleic Acid. It resides inside the nucleolus, which is in the nucleus of Eukaryotic Cells. In Prokaryotic Cells DNA free floats due to the cell's lack of a membrane. It is the blueprints to the many things a cell creates. Each section of DNA is called a nucleotide. A nucleotide is made of one phosphate molecule, one deoxyribose sugar molecule and one nitrogenus base. There are four types of nitrogenus bases. Thymine, Adenine, Guanine and Cytosine. Thymine only bonds with Adenine. Cytosine only bonds with Guanine. The specific order of Nitrogenus bases determines what the strand creates. The deoxyribose sugar and the phosphate create the sugar-phosphate backbone. The reason DNA twists is because of how the 3 components in a nucleotide bonds. Nothing in nature is usually perfect, and the 3 components must warp to be able to create a bond.
