During which phase of mitosis do the chromosomes form?
The answer is PROPHASE. there are four phases in Mitosis: prophase, anaphase, metaphase, and telophase.
What are the two main stages of meiosis?
The two main phases of meiosis are prophase and telophase
How many phases are in Meiosis?
5 stages in Meiosis IInterphase IProphase IMetaphase IAnaphase ITelophase I & Cytokinesis I;4 stages in Meiosis IIProphase IIMetaphase IIAnaphase IITelophase II & Cytokinesis II.
Crossing over occurs when?
During the early phases of meiosis
Which meiotic division is most like mitosis?
There are many similarities between meiosis and mitosis, and the phases are almost identical. The main difference between them is that there are two divisions in meiosis, and the chromosomes are not replicated in both of these.

Why are meiosis and mitosis confused?
Meiosis and mitosis are confused because iof the similarities in both the types of division.The similarities between mitosis and meiosis is that in both types of cell division -the cells divide to form daughter cellsDNA is replicated to form an extra setcentrioles move to the opposite end of the cell and form spindle fibers between themthe cell membrane, nucleolus and nuclear envelope all all break downthe chromosomes line up in the center of the cell and each spindle fiber is attached to the center of the chromosome by their centromerethe spindle fibres bring the chromatids to the opposite end of the cellin the ending phases of mitosis and meiosis the nuclear envelopes each contain half the amount of chromosomeboth the processes are a type of reproduction
What do the phases in meiosis do?
Prophase: coiling + shortening of the DNA into rods. the nucleolus and the nuclearmembrane break down.Metaphase: chromosomes line up in the middle of the cell.Anaphase: Chromatids of each chromosome separateTelophase: spindle fibers disassemble. chromosomes uncoilCytokinesis: the pinching inward of cell membrane. Cleavageis formed. Micro-filaments aid in splitting the cell.
What are The faces of mitosis and meiosis?
there are no faces in mitosis and meiosis but there are phases
Does meiosis occur in phases?
yes
What will these Spindle fibers eventually used for?
There are six phases of mitosis (a way which allows cell to reproduce itself so that organisms can grow). In this process, DNA is coiled into chromosomes. In the second phase, the spindle fibers attach themselves to centromere - centromere is a part of chromosome linking two sister chromatids (2 chromsatids make one chromosome). In the fourth phase, these spindle fibers shorten themselves and the sister chromatids are physically separated by the action. This way the two diploid daughter cells produced in mitosis have 46 chromosomes each.
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 are the two main stages of meiosis?
The two main phases of meiosis are prophase and telophase
Why are there two sets of phases during meiosis but only one during meiosis?
burr
