I need the answer today because i have to turned in tomorrow
plz help
1 I ALSO NEED TO name and explain the 3 parts of interphase.
2 what type of the cell enters the G.phase?Give an example.
3 why cant a damaged cell in the brain the replaced?
4 can chromosomes be seen clearly after the G2phase?
5 during what stage can chromosomes be seen clearly?
6 what forms to help and move chromatids to the opposite poles of the cell?
7 during what phase of the cell cycle does a lot of protein synthesis take place?
8 chromosomes are made of what molecule?what is the shape of this molecule?
9 when do chromatids line up at the equator of a cell?
10 do bacteria reproduce by mitosis?explain your answer.
11 when does the nuclear membrane and the nucleolus disappear? when do they reappear?
12 explain the difference in cytokinesis of a plant cell and animal cell.

They divide about once a day and spend about 22 hours in interphase.
The three parts of interphase are:
g1: proteins are produced
s: DNA is replicated
g2: more protein produced for use of atp.
brain cells can't be replaced because these cells lack the ability to divide because they are now specialized. (ie the lack the ability to go through mitosis)
spindle fibers form to pull to opposite poles
bacteria cannot go through mitosis (or meiosis for that matter). they divide via binary fission. they lack nuclear membranes. everything just happens in the cytoplasm of the cell. without the nucleus, mitosis/meiosis cannot be controlled or happen. bacteria replicate via asexual reproduction.
hope i helped a bit. i'm not going to answer all the questions.

I finished,I am getting a Big ''A'' tomorrow.
I don't need the answer any more but answer if you want answer it maybe somebody will need it.
