GEN-3000 Lecture Notes - Lecture 2: Sister Chromatids, Nuclear Membrane, Cell Membrane
Document Summary
*more info a bout sister chromatids vs homologous chromosomes. De ning cell stuctures and the di erences between eukaryotes and prokaryotes. 3 major groups of life: eubacteria-true bacteria, archaea (shares some traits with euks), eurkaryotes. *look at table on the slide show to see the di erences between prokaryotes and eukaryotes. **amount of dna does not tell you how complex an organism is. Chromosomes: structures in which an organism"s dna is arranged which serve as vehicles for transmitting genetic information. Chromatin: a network of chromosomes in the nucleus when cells are not undergoing division. Viruses: have genetic information however they are not cells. Plasma membrane: all cells are surrounded by this outer covering that de nes the cell boundary and delimits the cell from its immediate external environment. Cell wall: an outer covering in plants made of cellulose. Glycocalyx (cell coat): a covering over an animal cell plasma membrane consisting of glycoproteins and polysaccharides.
