 * Video 1. YouTube video about basic genetics from 23andMe** (http://www.youtube.com/watch?v=eOvMNOMRRm8) || =====Overview of Video (For Reference- No Need to Read if You Watch the Video)=====

====Nearly every __cell__ in the human body has a __nucleus__ which contains __DNA__, deoxyribonucleic acid. DNA is a two stranded molecule that is made of four different types of basepairs (A, T, C, G) that is coiled very tightly (3 billion pairs of it) such that it can fit into the nucleus. This tightly packed DNA makes up __chromosomes__ which contain the __genes__ (roughly 20,000 of them in a human). Ultimately, genes are translated into __proteins__ which determine the human __traits__. These traits may range from hair color, to blood type, to how a person responds to a medicine, to what diseases a person might have.====

====A human cell contains 23 sets of chromosomes (46 in all). Twenty-three come from the father of a child and 23 come from the mother. They are nearly exact replicas of each other with only small differences which determine which traits humans will have. These slightly different replicas of a gene are called __alleles__. In humans, the blood type gene is made of three alleles: A, B, and O.==== ||
