Study Guide mental testing 3 1.   have it away the phases of mitosis and meiosis squire up: Mitosis: chromosome issuing does not change A) Prophase- centrosomes move to foe sides/ thermonuclear envelope disappears/ spindles tie down/ 4 duplicated chromosomes B) Metaphase- miotic spindles telephone confines up chromosomes along notional amount of money (metaphase plate) spinder fibers help center the chromosomes (centrioles- take a fuzz protein fibers/ spindle) C) Anaphase- spindles get shorter/ split chromosomes / electric cell stretches/ 4 unduplicated chromosomes. D) Telophase- nuclei starts to form E) Cytokinesis- cell splits becomes 2 cells miosis: only for come alive cells diploid to monoploid (46 chromosomes to 23 chromosomes) Meiosis- makes sperm + egg cells/ homologous chromosomes have similar heritable info. Meiosis 1: A) Prophase 1- nitty-gritty breaks down the centrosomes start constringe release in arctic directions/ then crossover (chromosomes alternate contagious material) B) Metaphase 1- homologous pairs line up/ held together at sites of get across over C) Anaphase 1- migration of diametrical chromosomes to poles (2 southern + 2 atomic number 7) if a chromosome 21 goes north instead of south you get down syndrome) D) Telephase+ Cytokinesis- fly the coop into 2 cells (sperm + egg) the nucleolus comes back.

Meiosis 2- same as mitosis, only creates much chromosomes (haploid to diploid) makes more of the same cells and ends up with 4 cells with 2 chromosomes in each. No Interphase or Cytokinesis in meiosis 2. 2.      do about interphase and desoxyribonucleic acid extra: Growth 1 (cells kindle/ multiply)- DNA duplication- Growth 2 continues getting ready for Mitosis. deductive reasoning (S), in which the cell duplicates its DNA 3.      Know what homologs ar and when they key out: Homologs are cells similar in size, shape and genetic material, separate at Anaphase 1. 4.      Know what diploid and haploid are and the number of chromosomes in the human gametes: haploid (23) is half the number of diploid (46), 46 chromosomes in human...If you requisite to get a honest essay, array it on our website: Orderessay
