Presentation Transcript

  1. Animal Cell

  2. A Replicated Chromosome

  3. Diploid vs. Haploid • Diploid= 2 sets of chromosomes • One set from mom and one set from dad • Chromosomes come in pairs • Humans have 23 pairs of chromosomes • Haploid = 1 set of chromosomes • Sperm or egg has 23 single chromosomes

  4. same chromosomes (duplicated) in interphase prior to mitosis mitosis, cytoplasmic division chromosome (unduplicated) in daughter cell at interphase chromosome (unduplicated) in daughter cell at interphase chromosomes (unduplicated) in parent cell at interphase

  5. Metaphase chromosomes from a human female

  6. The Cytoskeleton

  7. Late Prophase Interphase Early Prophase pair of centrioles nuclear envelope Do not post to Internet

  8. Metaphase Anaphase Telophase Interphase Do not post to Internet

  9. Mitosis is over, and the spindle is now disassembling. Band of microfilaments at the former spindle equator contracts. The contractions continue and cut the cell in two. Cytokinesis

  10. A Duplicated Chromosome centromere one chromatid its sister chromatid One chromosome in the duplicated state In-text FigurePage 102

  11. Homologous Pair

  12. Meiosis Overview

  13. Crossing Over

  14. Meiosis

  15. Alternation of Generation
