Mitosis

Post by jiyuu » Mon Feb 13, 2006 9:19 pm

The term "mitosis" comes from the Greek word meaning "thread". Explain why this word may be helpful in describing this process of nuclear division.

What evidence is there that mitosis is a continuous process, not a series of separate events?

Thank you for any help!

It is called so because in mitosis, especially the prophase, sentriol produce spindle thread which then tie chromosomes in metaphase disk.

don't have idea for your second question.

because cells live, i mean spend its lifetime for growing and reproducting.
at autosome...
interphase is the keyword...
at interphase cells accumulate residues to do prophase...etc.

so that when you are looking the cell in microscope and the cell do not do all of prophase till telophase...
you are looking a cell which is doing reproduction process-i.e interphase.

Just a bit correction: not residues, but energy ;)

oh, yes.
in my head i just wanna to say
to increase the residues in the cell-the increase of the cell matrix,i.e. protoplasm, so that the cell can be at quite good condition to do reproduction-mitosis.

thanks for the correction...
