DNA Technology Human Genome Project (p454-455) (1) How many bases (base pairs) are their in the human genome? (2) How long did it take to determine the identity and sequence of all of the bases? (3) What as the primary source of DNA? and why? (4) What is a SNP? (5) How many genes in the human genome? (6) What can we learn if we compare the genomes of species? (7) How similar is the human genome to the chimpanzee genome? (8) How similar is the human genome to the mouse genome?
 * 3 million
 * 13 years
 * Sperm b/c it has a higher ration of DNA to protein than other cells.
 * Single nucleotide polymorphism
 * 25,000 genes
 * we can learn about how evolution
 * the genome of humans and the genome of chimpanzees are 99% alike.
 * the genome of a mouse is 88% similar to that of a human
