Document Summary
Lecture 1: movie stem cells revolution . Ancestor wondered about heredity, and they did some adaptation, domestication using the law of heredity. The diversity of living things slows down the process of development, and some guesses were forgotten, then rediscovered after a long time. Nineteenth century, pieces of indivisible genes control individual traits. 20th century, dna and rna were discovered form basic life units. Technique brought a more in-depth understanding: cells. 19th century biology advance: new cell arise only by the division of preexisting cells. Plasma membrane/ mitochondria/ cytoplasm/ e. r. / golgi bodies/ chloroplast/ solution of salts, sugars and proteins/ nucleus/ ribosome. Mitosis/meiosis and the cell cycle chromosomes/chromatin diploid/ haploid(germ cells) centromere, telomere, nucleolar organizers coalesced into nucleoli. Chromosome abnormality: burkitl"s lymphoma, segments of chromosome 8&14 exchanged, sign for cancer, wilm"s tumor: deletion of part of human chromosome 11. #1: down syndrome: three copies of chromosome 21. Bacterial chromosome: one piece, haploid, nonsexual reproduction: inheriting single traits.
