Day 7: Jumpin' Genes!
Mitosis & Meiosis in Action
These images caught cells in
different stages of mitosis. The cells are colored
with a combination of stains. The chromosomes are
stained blue. The mictrotubules making up the
mitotic spindle are stained green. The cell membrane
and certain components of the cytoplasm are stained
Clicking on any of the figures will download a

of all these images.
Early Prophase - The
chromosomes are coiling and condensing. The nuclear
membrane has dissolved.
Late Prophase - The
chromosomes are organizing between the two
Early Metaphase - The
chromosomes are being lined up along the metaphase
plate by mitotic spindle fibers.
Late Metaphase - The
metaphase plate can be clearly seen.
Early Anaphase - The
chromosomes are traveling toward either centriole
along the mitotic spindle fibers to which they are
Late Anaphase - The
centrioles begin to move apart and thus pull the
mitotic spindles fibers and their attached chromosomes
