Eukaryotic Cell Reproduction: Mitosis & Meiosis Mitosis: cell reproduction as long as growth in addition to replacement of cells. This makes identical copies (clones) Meiosis: cell reproduction as long as the production of gametes, such as egg in addition to sperm (sex cells) How many chromosomes in a human cell such as a skin cell How many chromosomes in egg in addition to sperm Human Karyotype Is this person male or female 46 46 46 Mitosis One division 46 46 46 chromosomes replication chromatids chromatids chromosomes chromosomes chromosomes 23 23 23 23 chromosomes Meiosis Two divisions

Mitosis: cell reproduction as long as growth in addition to replacement of cells. This makes identical copies (clones) What are some examples of mitosis in the body Cuts in addition to scrapes Embryonic growth Aging Stomach cells What are some examples of mitosis in other organisms Asexual reproduction (budding in addition to fragmentation) Plants: growth of roots in addition to stems Regeneration (starfish arm, lizard tail) 46 46 46 Mitosis One division 46 46 46 chromosomes replication chromatids chromatids chromosomes chromosomes chromosomes 23 23 23 23 chromosomes Meiosis Two divisions Sister Chromatids Chromosome Sister Chromatids DNA Replication centromere

Phases in Mitosis Interphase: DNA replication Prophase: chromosomes thicken, nucleus disappears Metaphase: chromosomes line up at center Anaphase: centromeres split, sister chromatids separate Telophase: cytokinesis, division of the cytoplasm

Applications of Mitosis Cancer = abnormal growth of cells Control of the Cell Cycle MPF is a protein that triggers mitosis. Where is MPF in high amounts in addition to in low amounts

Regulation of Cell Cycle What controls cell reproduction MPF = Maturation Promoting Factor MPF = cyclin + cdk (cdc2) Protein Kinase = activates other proteins i.e. spindle fibers that move chromosomes Two functions of MPF: 1. triggers mitosis 2. activates enzymes to breakdown cyclin (negative feedback)

Cancer Trans as long as mation = process that converts a normal cell to a cancer cell Tumor = loss of cell cycle control = abnormal growth of cells Benign = noncancerous, Malignant = cancerous Metastasis = spread rate of a malignant cancer to locations other than their origin (tumor cells enter blood vessels in addition to travel to other parts of the body) Meiosis: cell reproduction as long as the production of gametes, such as egg in addition to sperm (sex cells) Meiosis cuts the number of chromosomes in half Meiosis occurs in gonads Gonads are reproductive organs (such as ovaries in addition to testes) 2 divisions 1st Meiotic division 2nd Meiotic division Interphase Prophase II Prophase I Metaphase II Metaphase I Anaphase II Anaphase I Telophase II Telophase I

Homologous Pair (Homologous Chromosomes) Chromosomes that carry genes in the same place as long as the same traits One is maternal in origin (from the egg) The other is paternal in origin (from the sperm) Hair color Eye color Skin tone hitchikers earlobes widow’s 1st Meiotic Division Interphase: DNA replication Prophase I: crossing over Metaphase I: independent assortment Anaphase I: homologous pairs separate, centromeres intact Telophase I: cytokinesis 2nd Meiotic Division Prophase II: reorganization, no crossing over Metaphase II: chromosomes line up with centromere on line Anaphase II: centromere splits, sister chromatids separate Telophase II: cytokinesis
