well, I am in biology and I can't reall figure out how
long each phase lasts, prophase, metaphase, anaphase, and telophase?
In any population of actively dividing cells, only some are in mitosis. The
percentage of mitotic cells is the mitotic index. The duration of mitosis
can be approximated by multiplying the mitotic index by the duration of the
cell cycle. My experience (and its been a while) was that for mouse bone
marrow it was normally about 1.5-2.5 hours... if I recall correctly. I
believe there are lab experiments you can do on onion root tips in a high
school on this.
