  5. G1 S Interval of cell growth before DNA replication (chromosomes unduplicated) Interval of cell growth when the DNA is replicated (all chromosomes duplicated) cytoplasmic division; each daughter cell enters interphase G2 Interval after DNA replication; the cell prepares to divide Interphase ends for parent cell Fig. 8-5, p.128

  6. After mitosis and cytoplasmic division, the two daughter cells each have one (unduplicated) chromosome. Both daughter cells start life in interphase. mitosis, cytoplasmic division One of the unduplicated chromosomes in a parent cell at interphase The same two chromosomes, (duplicated) at interphase, prior to mitosis Fig. 8-6b, p.129

  7. pole microtubule of bipolar spindle chromosomes pole p.129

  8. a Cell at Interphase A diploid cell duplicates its DNA and prepares for mitosis. Fig. 8-7a, p.130

  9. pair of centrioles c Late Prophase The duplicated chromosomes continue to condense. New microtubules move one of two pairs of centrioles to the opposite side of the nucleus. The nuclear envelope starts to break up. Fig. 8-7c, p.130

  10. e Metaphase All of the chromosomes have become lined up midway between the spindle poles. At this stage of mitosis, the chromosomes are in their most tightly condensed form. Fig. 8-7e, p.130

  11. f Anaphase Sister chromatids separate as motor proteins moving along spindle microtubules drag them to opposite spindle poles. Other microtubules push the poles farther apart. Fig. 8-7f, p.130

  12. g Telophase There are two clusters of chromosomes, which now decondense. Patches of new membrane fuse to form a new nuclear envelope. Mitosis is over. Fig. 8-7g, p.130

  13. h Two Daughter Cells at Interphase After cytoplasmic division, there are two daughter cells. Each is diploid: Its nucleus has two of each type of chromosome, just like the parent cell. Fig. 8-7h, p.130
