Presentation Transcript

  1. “-omes” • Genome – Complete set of genetic information • Transcriptome – set of all the mRNA produced by a cell or an organism • Proteome – entire set of proteins coded for by the genome of a cell or an organism • How many chromosomes in human genome? 46 • Which is larger, genome or transcriptome? genome

  2. Mitosis • Occurs in which type of cells? Somatic • Occurs where in the body? Everywhere but gonads • Genetically identical (Clone) • Produces diploid daughter cells • Produces clones • Somatic cells

  3. Meiosis • Occurs in which type of cells? Sex cells • Occurs where in the body? gonads • Genetically different • Produces haploid daughter cells • Produces eggs or sperm • Produces Gametes

  4. Questions? • Which is more common mitosis or meiosis? Mitosis • What is the main way that prokaryote chromosomes differ eukaryotic chromosomes? Proks = no histones & circular • Binary fission or mitosis? • Fungi - mitosis • E. Coli – binary fission • Plants - mitosis • What percent of DNA is non-coding in humans? 97–98%

  5. Questions? (Page 2) • What is the genome? all the genes of an organism • What is larger proteome or genome? genome • Haploid or Diploid? • Red Blood Cell 2n • Muscle Cell 2n • Sperm n • Neuron 2n • Macrophage 2n • CD4 T-Cell 2n

  6. Questions? • What are the phases of the cell cycle? • G1, S (DNA replication), G2, M (Cell Division) • What are the parts of interphase? • G1, S (DNA replication), G2 • What are the parts of mitosis? • Prophase, Metaphase, Anaphase, & Telophase • What happens during the S-phase? • DNA Replication

  7. Questions (Page 2) • What is a CdK? Cyclin Dependent Kinase – regulates cell cycle • What is the G0 phase? Nondividing phase • How is cytokinesis different in animal cells from plant cells? Cleavage furrow (Animal) or Cell plate (Plant) • When does cytokinesis occur in the cell cycle? At the end of mitosis, during telophase • How does a kinetochore differ from a centromere? • Kinetochore is a protein surrounding the centromere region of the chromosome
