1 Cell Division NOT on Exam 1 Exam will only cover Scien8fic Method to Photosynthesis Cell Theory 1) All living things are made up of cells 2) All cells come from pre-existing cells 3) The cell is the fundamental unit of structure and function in all living organisms 4) Energy Dlow occurs within cells 5) Cells contain hereditary information which is passed from cell to cell during cell division 6) All cells are basically the same in chemical composition Cell Theory 1) All living things are made up of cells 2) All cells come from pre-existing cells 3) The cell is the fundamental unit of structure and function in all living organisms 4) Energy Dlow occurs within cells 5) Cells contain hereditary information which is passed from cell to cell during cell division 6) All cells are basically the same in chemical composition 1
2 Using the knowledge you already have 1) on each of the green papers, write in the top left corner one of the following: interphase gap 2, interphase gap 1, interphase synthesis. 2) on each of the blue papers, write in the top left corner one of the following: miotic phase: anaphase, miotic phase: metaphase, miotic phase prophase, miotic phase telophase, cytokinesis. DNA usually stringy DNA blocked into Chromosomes during division(more about this later) Now place this in the order you think they should go on a new sheet of paper for In Class Wrap-up #6. Homologous chromosomes: Chromosomes that are essentially the same, but with different alleles 22 pairs in males 23 in females 2
3 Homologous chromosomes: Chromosomes that are essentitally the same, but with different genes 22 pairs in males 23 in females X and Y differ in males X and Y are sex-chromosomes Homologous chromosomes: Chromosomes that are essentitally the same, but with different genes 22 pairs in males 23 in females X and Y differ in males X and Y are sex-chromosomes Autosomes are 1-22 and are non-sex chromosomes DNA duplicated and thus chromosomes duplicated (sister chromatids) Interphase G1 (Gap 1) Phase S (Synthesis) Phase G2 (Gap 2) Phase 3
4 Mitotic Phase Prophase DNA already duplicated, forms into chromosomes Microtubules begin forming Metaphase Anaphase Sister chromatids separated (becoming chromosomes) and moved to opposite poles 4
