Detailed Study of the Text Words amp。 the discovery of human birthplace。 and it creates the first genetic map of the world. In the process of collecting information for the book, however, scientists encountered great difficulties. The ultimate goal of their work is to remove racial prejudice. The passage falls into four parts. Part 1 (Paras. 12) Two scientific aims achieved by the book:No scientific basis for racial prejudice。 another is to show that under the skin we are all very similar on a genetic level. 3)What is the ultimate aim of the book?The book is written for scientific purposes as well as in hopes that it would have a social effect by proving that there is no biological basis for racial prejudice, thus disproving the idea that one race is genetically superior to any other race. 4)Where is the information needed to draw a global family tree found?It is found in human blood: various proteins that serve as markers to reveal a person’s genetic makeup.5)What can genetic information can tell us?In addition to telling us about our origins, genetic information is also the latest raw material of the medical industry, which hopes to use human DNA to build specialized proteins that may have some value as diseasefighting drugs.II. Background informationLuca CavalliSforza: born in Genoa, Italy, was educated at the University of Pavia where he gained his MD in 1944. After working on bacterial genetics at Cambridge (1948-1950) and Milan (1950-1957) he has held chairs in genetics at Parma (1958-1962) and Pavia (1962-1970). In 1970 he was appointed professor of genetics at the University of Stanford, California, a position he held until his retirement in 1992. CavalliSforza has specialized mainly in the genetics of human populations, producing with Walter Bodmer a prehensive survey of the subject in their Genetics, Evolution and Man (1976). He has also done much to show how genetic data from present human racial groups could be used to reconstruct their past separations. This reconstruction, based on the analysis of 58 genes, yields a bifurcated evolutionary tree with Caucasian and African races in one branch and Orientals, Oceanians, and Amerinds in the other. The human genetic map: Our bodies are prised of trillions of microscopic units called cells. Cells in turn are built up from many specific types of molecules, both large and small. The large molecules or macromolecules include polysaccharides, nucleic acids and proteins. Proteins are the workhorses of our cells. There are about 40,000 different types of proteins in our bodies. Each protein is present in many, many copies. An adult, for example, carries about 1021 (a billion trillion) hemoglobin molecules. The flow of genetic information is from DNA to RNA to Protein. Each protein is a linear polymer of a specific sequence of 20 different amino acids. DNA is also a linear polymer prised of 4 types of nucleotides. The sequence of amino acids in each protein is encoded by a segment of DNA called a gene. Three consecutive nucleotides in a gene encode a single amino acid in the corresponding protein. The genetic code is universal among all living things. Basques: The Basques are a people who live in a small region (about the size of Rhode Island in the United States) that straddles the border of Spain and France from the sea in the west into the Pyrenees in the east. This area is called Euskal Herria (prising seven provinces, historically: Araba, Bizkaia, Gipuzkoa, and Navarra on the Spanish side。 B exercises after class.3. Supplement More Exercisesi.

Topic for discussion: Do you agree with sharing personal genetic information online? (open discussion)The teacher’s offer: Thanks to social networking sites set up by personal genomics panies, one can share genetic information with family, friends and even strangers on the internet. Bonding over a similar genetic background sounds relatively harmless, but sharing genetic information online raises a host of ethical questions. Firstly, because genetic information applie
