∙ 14y agoThe chromosomes condense. Imagine a white thread in a white bowl, all unraveled. It's hard to see the thread, and it's very fine. It takes up a lot of space because it's not folded up or anything, just in a haphazard cluster in the bowl. This is how the DNA is before the chromosomes start condensing. Imagine tying and folding the string into a rope. The rope is now visible and takes up less space even though there's still the same amount of thread.
The chromosomes themselves condense by winding and folding or even coiling around clusters of proteins called histones.

∙ 13y agoThe process of cell division is called mitosis. Chromosomes only form when a cell is about to split. Then centrioles in the cell move to two opposite ends of the cell, connected to each chromosome. Then the chromosomes are split in half.

Why do chromosomes split?
Chromosomes split during cell division (mitosis or meiosis) to ensure that each daughter cell receives a complete set of chromosomes. This process, called chromosome segregation, allows genetic information to be accurately replicated and transmitted to the next generation of cells.
What occurs with chromosomes in the parent cell with the resulting daughter cell?
Mitosis, or the splitting of one cell, results in the two identical copies of the first cell. The chromosomes are also split during the anaphase.
What happens to the chromosome before an animal cell divides?
The chromosomes have to split and go to opposite sides of the cell.
Why does a sex cell not receive both chromosomes from a pair normally in grasshoppers?
Because in the events of Meiosis the chromosomes split and then the sex cell only has half the number of chromosomes. Once the sperm & egg unite (fertilization) then the chromosomes pair up, and you get all 46 chromosomes.
What is the function of a centiole?
It attaches to chromosomes and split them evenly to both sides of the dividing cell.
What is DNA packed into when a cell is ready to reproduce?
chromosomes

Will mitosis create a mosquito cell with 6 chromosomes?
Yes, mosquitos have six cells in their chromosomes. So, at the end of mitosis, the cell will have six chromosomes. To begin with, the cell will split so there are three chromosomes in each gamete.
How many chromosomes do daughter cells have'?
A normal cell has 46 chromosomes so when they split the chromosomes divide as well. So it's 46/2 which is 23. A daughter cell has 23 chromosomes. (: I juss learned that in Biology this yearr.

What are the two phases of the cell?
There are actually 5 steps of mitosis - Steps 1: the nucleus disappears and chromosomes start to appear. 2: the chromosomes make copies of themselves. 3:the chromosomes line up in the middle of the cell. 4:the chromosomes split and are pulled to both ends of the cell. 5:the cell splits.
Describe the chromatids that make up a chromosome when a cell is ready to divide.?
Describe the chromatic that make up a chromosome when a cell is ready to split
What would happen to the number of chromosomes in a cell if mitosis occurred but cytokinesis did not take place?
The chromosomes would still duplicate, but the parent cell wouldn't split into the two daughter cells.
