Document Summary
Where one word is used to talk about two different things; the techniques used to study the two are different: genetics is the study of biology at the level of the gene (watson & crick) Biology work is done by proteins (enzymes, pumps and channels), lipids, and carbohydrates. Looking at genes is both an advance and a step backwards: Disadvantage: if you want to understand biology and behaviour, proteins are closer to the things that you want to understand than are genes. The two opposing sequences make it a double helix (not shown). There are four bases: c, g, a, t. The information on bottom strand is redundant (if you have the information on the top, you can infer what is on the bottom). Exon: shown as boxes; represents sequence that will eventually code for the protein. Intron: shown as lines connecting boxes; represents sequence that will not code for the protein.
