What is the major difference between anaphase and metaphase?
Anaphase is the stage of cell division where sister chromatids separate and move towards opposite ends of the cell, pulled by the spindle fibers. Metaphase is the stage where chromosomes align at the cell's equator before they separate in anaphase.
Which stage of a cells cycle do the replicated chromosomes line up on the equator of the cell?
The replicated chromosomes line up on the equator of the cell during metaphase of mitosis. This is when the spindle fibers attach to the centromeres of the chromosomes and align them at the center of the cell before they separate during anaphase.
What phase of mitosis does the cell contain four chromosomes?
The phase of mitosis where the cell contains four chromosomes is known as metaphase. During metaphase, the chromosomes align along the metaphase plate in the center of the cell before being separated into two sets during anaphase.
What has occurred at the end of Prophase?
At the end of prophase all of the chromosomes(chromatids joined at the centromere) are now floating around the cells and the spindle fibers are formed. Then you go into Metaphase where the chromosomes line up in the center of the call and the centromeres attach to the spindle fibers. Hope that helped!:)
What would happen if one or more spindle fibers failed to form from one spindle apparatus?
Since spindle fibers are involved in separating chromosomes and centrosomes duringmitosis, you would have impaired mitosis. The spindle is largely made of organized microtubules, which help chromosomes line up during metaphase and then separate during anaphase. The cell has many "checkpoints" which will check to make sure that chromosomes are properly lined up and attached before they can be separated. If the spindle fibers are not properly formed, it would be harder to get past the checkpoint, and so mitosis would be delayed or would not occur at all. If there are mutations in checkpoint proteins (such as in cancer cells), mitosis may proceed but the chromosomes may not be separated normally (resulting in "aneuploidy").They would die because spindle fibers isn't for indiviuals itz mostly dealing with the different phases of mitosis
What is the phase of mitosis if chromosomes attach to the spindle fibers?
The phase of mitosis when chromosomes attach to the spindle fibers is the metaphase. During metaphase, the chromosomes align along the equatorial plane of the cell before being separated and pulled to opposite poles during anaphase.
What phase do chromosomes attach to spindle fibers?
Chromosomes attach to spindle fibers during metaphase of mitosis. This attachment ensures that the chromosomes are properly aligned at the metaphase plate before they are separated and pulled to opposite poles of the cell during anaphase.
During metaphase the centrometers attach to what structures?
During metaphase, the centromeres of chromosomes attach to spindle fibers (microtubules) that extend from opposite poles of the cell. This attachment helps properly align the chromosomes along the metaphase plate in the center of the cell before they are separated in anaphase.
What is the major difference between anaphase and metaphase?
Anaphase is the stage of cell division where sister chromatids separate and move towards opposite ends of the cell, pulled by the spindle fibers. Metaphase is the stage where chromosomes align at the cell's equator before they separate in anaphase.
During which phase of mitosis do the paired chromatids break apart at the centromere to become individual chromosomes before moving toward opposite poles of the cell?
The chromatids break apart at the centromere during the anaphase of mitosis. This is when the spindle fibers pull the individual chromosomes toward opposite poles of the cell.
When do the spindle fibers shorten?
Spindle fibers shorten during anaphase I and anaphase II in meiosis in order for both the separation of the homologous chromosomes and the sister chromatids to opposite poles before telophase I and II. After cytokinesis, the end result would be four daughter cells, otherwise known as the tetrad, being produced with half the number of chromosomes as compared to the parent cell. In mitosis, spindle fibers attached to the kinetochores of the chromosome shorten only during anaphase to separate the sister chromatids away from the centromere to opposite poles in preparation for cytokinesis where there would be a cleavage furrow deepening at the equator of the cell. The end result of mitosis are two daughter cells with identical number of chromosomes as the parent cell.
Which stage of a cells cycle do the replicated chromosomes line up on the equator of the cell?
The replicated chromosomes line up on the equator of the cell during metaphase of mitosis. This is when the spindle fibers attach to the centromeres of the chromosomes and align them at the center of the cell before they separate during anaphase.
How do you describe each phase of mitosis?
Soon before interphase ends, the chromosomes duplicate. During prophase, the chromosomes line up in their pairs. Metaphase has the chromosomes centering to be split, while anaphase splits the chromosomes apart. Telophase forms the new nuclei, and finally divides the cell into two.
What are chromosome pairs attached to?
Pairs of chromosomes are not attached. Before mitosis chromosomes replicate themselves, these twin identical chromosomes are attached at the centromere. before cell division the cell has 46 chromosomes (23 pairs) but has 2 copies of each individual chromosome called chromatids,(making a total of 92 chromosones, 46 for each daughter cell) which are joined at the centromere giving the characteristic X shape. Pairs are not joined, chromatids are.
What phase in meiosis does the double stranded chromosomes move to the center of the cell and separate?
The phase you are referring to is metaphase I. In metaphase I of meiosis, homologous pairs of chromosomes line up at the cell's equator before they are separated and pulled to opposite ends of the cell during anaphase I.
What phase of mitosis does the cell contain four chromosomes?
The phase of mitosis where the cell contains four chromosomes is known as metaphase. During metaphase, the chromosomes align along the metaphase plate in the center of the cell before being separated into two sets during anaphase.
Describe the 6 stages of mitosis?
Prophase: in this stage of the mitosis the nuclear envelop disentigrate, and the centeoles began forming on both sides of the cell, and the spindle fibre form Metaphase: in metaphase the spindle fibre attach to the centromere and the chromosomes lined up in the middle of the cell. Anaphase: Telophase
