  1. the chromosomes coil around proteins
    histones
  2. each individual Dna-histone spool
    nucleosome
  3. where two sister chromatids are connected
    centromere
  4. a copy of a cell; two double-stranded DNA molecules that are attached to each other
    sister chromatids
  5. nuclear division mechanism that occurs in stomatic cells of multicelled eukaryotes
    mitosis
  6. stomatic cells
    body cells
  7. nuclear division mechanism that precedes the formation of gametes or spores
    meisios
  8. What are human gametes?
    sperm and egg cells
  9. How do prokarotes reproduce?
    prokaryotic division
  10. What cells have to inherit parental DNA and enough cytoplasm to start living on their own?
    daughter cells
  11. a series of events from one cell divison to the next
    cell cycle
  12. the sum of all chromosomes in a cell of a given type
    chromosome number
  13. how often do red blood cells divide?
    every 12 hours
  14. In what stage of interphase are neurons arrested
    G1
  15. stage of interphase: intervall of cell growth and activity before the onset of DNA replication
    G1

  17. Stage if interphase:
    Cell prepares for division by synthesizing proteins that drive mitosis

    C4
  25. What kind of plants have their carbon fixed twice and their reactions are seperated temporally
    CAM
  26. What kind of plants do very well in arid environments?
