Document Summary
Last week: horrors of nazi race hygiene program influenced a retreat from race and a focus on using science to challenge racism. Biologists focused on the greater geneteic variation within races than between them. American anthropologists argued that human differences are primarily cultural, not biological. Human genome project ( hgp) : research effort focused on creating a map locatin all human genes. Project began in 1990; draft announced in 2000, complete in 2003. Volunteers near laboratories contributed dna samples for sequencing; identities of the. Dna, or deoxyribonucleic acid, carries the genetic code. Nucleotide: molecules forming the structure of dna; made up of a phosphate group, sugar and a base. Gene: sequence of nucleotides that codes for a polypeptide ( chain of amino acids making up a protein) Central dogma of molecular biology: presumed direct relationship between genotype ( genetic make up) and phenotype ( observable traits) Announcements of the hgp were accompanied by comments on race:
