Psalm 139 describes man as “wonderfully and fearfully made.”
Every one of us carries the assembly instructions for his own body. The cells in our bodies contain this information stored in each cell’s genetic material. Deoxyribonucleic acid or DNA is the molecule that holds these instructions controlling the development and functioning of our bodies. In fact, DNA does this in all known living organisms.
DNA is often compared to a set of blueprints. This is because it contains the information necessary to build the components of our cells, molecules such as proteins and ribonucleic acid (RNA). DNA takes the form of a polymer made up of simpler units called nucleotides which are in turn held together by a backbone of sugars and phosphates. Each sugar is attached to one of four types of molecules called “bases.”  The physical structure of the DNA molecule is usually referred to as a “double-helix.” Imagine a long ladder that has been twisted so that the side rails form a pair of spirals tied together by the rungs. In DNA the sugars and phosphates make up the spiral rails, and each rung is made up of a pair of the bases. The sequence of the base pairs along the DNA molecule encodes the information being stored.
