what do we mean by the term interphase?
This is a phase of the cell cycle in which a typical cell spends most of its life
100
What happens in the prophase in mitosis?
Chromosomes become visible, the nucleus disappears, the mitotic spindle forms and the nuclear envelope disappears.
100
What happens in metaphase 2 during meiosis ?
The chromosomes become arranged on the metaphase plate.
100
What does Anaphase mean according to cell biology?
It means when the chromosomes of each bivalent separates and start to move towards the opposite poles of the cell as a result of the action of the spindle.
100
What happens in cytokinesis?
The cell membrane move inward to create two daughter cells each having its own nucleus with identical chromosomes.
200
During the interphase what happens?
The cell copies its DNA in preparation for mitosis.
200
At which cell division does the mitosis begin?
Prophase
200
Is metaphase 2 haploid or diploid?
Haploid since it has 2 duplicated chromosomes 1 long and 1 short and they are all one copy.
200
What happens in anaphase 2?
The sister chromatids separates and now-daughter chromosomes move to the opposite pole of the cell.
200
When does Cytokinesis occur?
After mitosis.
300
A human cell ordinarily will have 23 pairs of chromosomes, for a total of 46 chromosomes. what will the cells have at the end of a cell cycle?
23 pairs of chromosomes, 46 total
300
mitosis and meiosis are both processes in which a cell divides and creates new cells. mitosis produces normal body cells. what type of cell does meiosis produce?
Gametes
300
What happens to the chromosome number during meiosis?
It reduces
300
the time between cell division in the life cycle of the cell is called?
interphase
300
how does meiosis differ from mitosis?
meiosis produces 4 genetically different haploid cells. Mitosis produces 2 genetically identical diploid cells.

is just backwards compared to mitosis 


is shorter version of mitosis



has more steps than mitosis

What happens during S phase in the duration of the interphase cycle?

Damage to DNA is detected and fixed during S-phase.

500
During which phase of mitosis do the chromosomes line up in the middle of the dividing cells?
Metaphase
500

phase of mitosis where nuclear membrane reforms and the spindle fibers disappear

Telophase
500

A protein called p53 can keep cells from dividing. To prevent cell division, this protein most likely stops what?

Mitosis
