(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? Genetic Engineering (p460-463) (9) Define: transgenic organism (10) Describe how we can use transgenic bacteria. (11) Describe how we can use transgenic plants. (12) Describe how we cna use transgenic animals.

1. There are 3,000,000,000 base pairs in the human genome. 2. It took researcher 13 years to correctly identify and sequence all of the bases. 3. The promary source of DNA is sperm, due to its high DNA to protein ratio. 4. SNP stands for Single Nucleotide Polymorphisms. 5. There are 25,000 genes in the human genome. 6. If genomes of species are compared, we can learn how species have evolved over time. 7. The human genome is 99% identical to the chimpanzee genome. 8. The human genome is 88% identical to the mouse genome. 9. Transgenic organisms have a foreign gene added into them. 10. Transgenic bacteria can be used for medicines, such as insulin and hormones. 11. Transgenic plants can be used to create plants that are immune to harmful outside forces. 12. Transgenic animals can be made larger, more immune to outside forces, and more suited for their environments.
