You are watching: What is the purpose of the spindle fibers
The strands room suppose come be specifically same once replication is complete, for this reason you would certainly not have the ability to tell the difference.
Has a solid secure nucleus, other than moving DNA. The cell would certainly be eukaryotic, and also you would certainly not be able to see any type of chromosomes in the nucleus. The genetic material is presented as a chromatin.
The spindle is vital to equally divide the chromosomes in a parental cell into two daughter cells throughout both varieties of atom division; mitosis and also meiosis.
At this point, the spindle fibers farming out of the poles resemble a star-shaped structure. What is this structure called?
An easy means to mental this is to know that they meet at the center and also that they line up along the equator.
This helps through cell division because it enables the parent cell separation into two daughter cells, which will certainly be similar in size
The chromosomes arrive at the poles, then fragments of the atom membrane assemble roughly the 2 chromosomes, which forms a brand-new nuclear membrane about the cells
Chromosomes end up being visible, while the nuclear source disappears, the mitotic spindle forms, and the atom envelope disappears
The cleavage furrow is the indentation of the cell"s surface ar that begins the development of cleavage, by which animal and some algal cell undergo cytokinesis, the final splitting of the membrane, in the process of cabinet division
Plant cells do not have centrioles or asters. Tree cells division by a cell plate that eventually becomes the cabinet wall
Mitosis to produce cells and if the cell splits down the center it would split the chromosomes and have two cells.

What go mitosis perform that the cell would do wrong if that just split down the center in cabinet division?
Mitosis is just an easy cell division leaving two the same cells, a.k.a. The daughter cells, and there is just one division. They have actually identical DNA come its parent cells. Dividing in the middle of the division is not possible.
Why is it crucial to replicate the chromosomes throughout the S (synthesis) phase before mitosis begins?
It is vital to replicate the chromosomes during the S phase before mitosis begins because without it over there wouldn"t be enough DNA to be split into daughter cells
A common organic study specimen, the fruit fly, has 4 pairs of chromosomes in each cell. As it grows, the reproduces more cells via mitosis. How numerous chromosomes would you expect to discover in each brand-new cell?
Number the adhering to steps in the exactly order and also tell which stage it occurs in: (a.) A cleavage furrow or cell plate forms, separating the nuclei(b.) Chromosomes line up at the equator and also chromatids room attached to spindle fibers(c.) nuclear membrane and also nucleolus reappear(d.) genetic material replicates and is joined at the centromere(e.) Centromeres divide and also single-stranded chromosomes move to the poles
1. Hereditary material replicates and also is joined at the centromere (Prophase)2. Chromosomes line up in ~ the equator and chromatids are attached to spindle fibers (Metaphase)3. Centromeres divide and also single-stranded chromosomes move to the poles (Anaphase)4. Nuclear membrane and also nucleolus reappear (Telophase)5. A cleavage furrow or cell plate forms, separating the nuclei (Cytokinesis)
