Document Summary
1865 discovery of discrete units of inheritance (peas) 1911 discovery that genes could be mapped in order along length of chromosomes. 1944 discovery of dna as genetic material. 2017 ma(cid:374)(cid:455) ge(cid:374)o(cid:373)es (cid:272)o(cid:373)pletel(cid:455) se(cid:395)ue(cid:374)(cid:272)ed, (cid:862)bioi(cid:374)fo(cid:396)(cid:373)ati(cid:272)s/ co(cid:373)putatio(cid:374)al ge(cid:374)o(cid:373)i(cid:272)s(cid:863) (cid:272)o(cid:373)es of age. Used plants (peas) with complete flowers (with both male & female reproductive structures) Most organisms are diploid: two copies of each gene. Pollen contains sperm carpel may contain many ovules (containing eggs) multiple fertilization events occurs. Heterozygous: alleles differ (one dominant, one recessive carrier) Protein polymer: 20 different aa building blocks (proteins are much more complex, but turns out its dna that is the genetic material) Tudies of (cid:448)i(cid:396)ule(cid:374)t st(cid:396)ai(cid:374)s of sho(cid:449)ed that a (cid:862)t(cid:396)a(cid:374)sfo(cid:396)(cid:373)i(cid:374)g p(cid:396)i(cid:374)(cid:272)iple(cid:863) (cid:272)ould (cid:271)e passed f(cid:396)o(cid:373) o(cid:374)e (cid:271)a(cid:272)te(cid:396)ia to a(cid:374)othe(cid:396), a(cid:374)d that dna carries the information.
