  1. PROPHASE
    SPINDLES BEGINS TO FORM

    NUCLEOLI DISAPPEAR

    SISTR CHROMATIDS JOIN

    (BUNCH OF WORMS)
  2. PROMETAPHASE
    NUCLEAR MEMBRANE DISSOLVES

    KINETOCHORES ATTACH TO SPINDLE
  3. METAPHASE
    KINETOCHORES ATTACHED TO SPINDLE FIBERS

    CHROMOSOMES BEGIN TO ALIGN DOWN CENTER OF CELL
  4. ANAPHASE
    KINETOCHORE MICROTUBLES SEPERATE CROMOSOMES TO OPPOSITE POLE
  5. CYTOKINESIS
    OCCURS DURING/AFTER TELOPHASE

    DIVISION OF CYTOPLASM
  6. CYTOKINESIS DIFF IN PLANT & ANIMAL CELLS
    ANIMAL: CELL CLEAVAGE

    PLAN:CELL PLATE DEVELOPS IN ORDER TO DIVIDE CYTOPLASM
  7. REPRODUCTION
    BIRTH NEW CELLS

    OCCURS MORE OFTEN IN CELLULAR LEVEL
  8. EURAYOTES REGENERATE
    MULTIPLE STEP CALLED MITOSIS
  9. CELL DIVISION/MITOSIS CRITICAL
    TISSUE RENEWAL

    GROWTH/DEVELOPEMENT

    REPRODUCTION
  10. INTERPHASE
    accounts for 90% of the cycle. copies its chromosomes and prepares for cell division
  11. (G1) phase
    GAP 1 PERIOD AFTER MITOSIS/BEFORE THE BEGINNING OF DNA SYNTHESIS

    PREPARATIONS FOR COPING DNA
  12. (S) phase
    SYNTHESIS TIME WHEN THE CELLS DNA IS REPLICATED
  13. (G2) phase
    G2 IS TIME AFTER S AND PRIOR TO MITOSIS

    CELL DOUBLES IN SIZES/DOUBLES AMOUNT OF CYTOPLASM AND ORGANELLES
  14. (G0) PHASE
    STAGE BEFORE DNA REPLICATION

    CELLSARE ARRESTED IN A NON DIVIDING STAGE
  15. INTERPHASE-IN ORDER FOR MITOSIS TO OCCUR MUST FIRST DUPLICATE ITS GENOME
    GENOME COMPLETE SET ORGANISMS GENES

    LOCATED ON CHROMOSOMES CELLS NUCLEUS
  16. CHROMOSOMES
    CONTAIN GENETIC MATERIAL

    MADE OF CROMATIN (COMBINATION OF DNA& PROTEIN ELLS

    NOT VISIVLE IN A CELL UNTIL CELL DIVISION
  17. # OF CHROMOSOMES
    HUMAN SOMATIC CELLS 46 CHROMOSOMES (DIPLOID CELLS)

    HUMAN GAMETES(EGG/SPERM) 23 CHROMOSOMES (HAPLOID CELLS)
  18. CHROMOSOMES CONSIST OF
    SINGLE DOUBLE STRANDED MOLECULE DNA

    TO REPLICATE DNA MUST BE TIGHLY WOUND INTO CHROMOSOMES
  19. DNA
    COILDS AROUND A 8 HISTONES PROTEINS TO FORM A NUCLEOSOME ->COIL FURTHER INTO SUPERCOILS
  20. HISTONES
    HISTONE PROTEINS ARE +CHARGED ATTRACT THEM TO PHOSPHATE GROUPS OF DNA NEGATIVELY CHARGED
  21. CENTROMERE
    A PINCHED REGION IN A CHROMOSOME

    CONTAINS SPECIC DNA BOUND TO A DISK PROTEIN KINETOCHORE
  22. MITOSIS
    • PROPHASE
    • PROMETAPHASE
    • METAPHASE
    • ANAPHASE
    • TELOPHASE & CYTOKINESIS
  23. TELOPHASE & CYOKENESIS
    NUCLEOLUS FORMING

    CLEVAGE BURROW

    NUCLEAR ENVELOPE FORMING
  24. INTERPHASE
  25. METAPHASE
  26. ANAPHASE
  27. TELOPHASE & CYTOKINESIS
  28. PROMETAPHASE
  29. PROMETAPHASE
  30. GENOME
    GENETIC INFORMATION
  31. CHROMATIN
    ENTIRE COMPLEX OF DNA AND PROTEIN THAT IS THE BUILDING MATERIAL
  32. SISTER CHROMATIDS
    JOINED COPIES OF ORIGINAL CHROMOSOME

    IDEANTICAL A MOLECULRE
  33. MIOTIC SPINDLE
    BEGINS TO FORM IN THE CYTOPLASM DURING PHASE
  34. CENTROSOME
    A SUBCELLULAR REGION CONTAINING MATERIAL THAT FUNCTIONS THRUGHOUT THE CELL TO ORGANIZE THE CELL MICROTUBULES
  35. ASTER
    A RADIAL ARRAY OF SHORT MICROTUBULES EXTENDS FROM EACH CENTROME
  36. KINETOCHORE
    STRUCTURE OF PROTEINS ASSOCIATED WITH SPECIFIC SECTIONS OF CHROMOSOMAL DNA

    FACE OPPOSITE DIRECTION
