Anaphase and telephase-Anaphase begins when the paired centromeres of each chromosome separate, liberating the sister chromatids, which begin moving toward opposite poles of the cell. At telophase, the chromosomes have reached the poles and daughter nuclei form.

How will chromosome segregation be affected if the centrioles are mispositioned in the cell and a functional mitotic spindle fails to form?

Sister chromatids will not be divided equally among daughter cells.


What happens to sister chromatids in meiosis?

They are separated and pulled to the opposite ends, or poles.


2. What are sister chromatids When do the separate?

In anaphase I the sister chromatids remain attached, while in anaphase II the sister chromatids separate.


What is the primary functional differences between mitotic anaphase and meiotic anaphase II?

In mitotic anaphase, sister chromatids separate and move towards opposite poles of the cell, resulting in genetically identical daughter cells. In meiotic anaphase II, homologous chromosomes have already separated in meiosis I, so sister chromatids now separate and move towards opposite poles, resulting in haploid daughter cells with genetic variation.


When do the centromeres split and form the chromatids?

Centromeres split during cell division in the mitotic phase called anaphase. As the sister chromatids are pulled apart towards opposite poles of the cell, the centromeres divide, forming individual chromatids that will become separate chromosomes in the daughter cells.


How many different kinds of cells are produced at the end of a single mitotic division?

Two identical daughter cells are produced at the end of a single mitotic division.


What happens to the amount of chromosomes during cell division?

During cell division the chromosomes are copied and they form sister chromatids. Then the mitotic spindle attaches to the sister chromatids and pulls them apart, splitting the nucleus in two. Then the cell goes through cytokenesis and the cell membrane is pinched together in the center, this divides the organelles and the cytoplasm between the two daughter cells.


Copies of chromosomes liked together at their centromeres at the beginning of meiosis are called what kid of chromatid?

At the beginning of meiosis, copies of chromosomes linked together at their centromeres are called sister chromatids. These sister chromatids are duplicated copies of a single chromosome and are held together by proteins called cohesins.


Which molecules is critical for the proper separation of sister chromatids?

The molecule critical for the proper separation of sister chromatids is called cohesin. Cohesin is a protein complex that holds the sister chromatids together during cell division. It helps ensure that the sister chromatids are accurately and evenly separated into two daughter cells.


How do cells produced at the end of Telophase II compare to the cells that started the process?

Starting cells have two chromatids in each chromosome while end cells have single chromatids .


How do you chromosomes at end of meiosis i compare with the chromosomes at end of meiosis ii?

At the end of meiosis I, the chromosomes are duplicated (sister chromatids) and homologous chromosomes separate. At the end of meiosis II, the sister chromatids separate, resulting in four haploid daughter cells each with a single set of chromosomes. Meiosis II is similar to mitosis in terms of chromosome behavior as the sister chromatids separate.


Which of the two meiotic divisions is similar to the first mitotic division?

Yes, in that the sister chromatids of the homologous chromosomes separate into four new daughter cells. However, the result is four genetically non-identical daughter cells with only one set of 23 chromosomes.
