If the chromosomes didn't separate during anaphase what would the new nuclei look like?

If the centromeres did not split and the chromatids did not separate during anaphase, the cell would not become stretched. Also, the cell would be unable to go onto the next stage of mitosis, telophase, in which the chromosomes begin to stretch out and lose their rod-like appearance. The cell would remain as one, and be unable to split.

Which sequence is correct for mitosis?
Chromosomes form (prophase),Chromosomes line up (metaphase),Chromosomes separate (anaphase) ,Nuclei form (telophase)
How many chromosome are there in human intestinal cell at anaphase?
During anaphase in a human intestinal cell, there are 92 chromosomes. During anaphase, the 92 chromosomes are separating into two sets of 46, so that at the end of mitosis, there will be two genetically identical nuclei, each containing 46 chromosomes. As the new nuclei are forming, the cytoplasm splits in the process of cytokinesis, resulting in two genetically identical daughter cells, each having 46 chromosomes.
When is the cells chromosomes divided into two new nuclei?
Telophase
Why are Chromosomes called Double Chromosomes?
After DNA replication, there are double the number of chromosomes, which will be divided into two identical daughter nuclei during mitosis. For example, a normal human body cell has 46 chromosomes. When it undergoes DNA replication, the chromosomes are doubled so that there will be 92 chromosomes, consisting of 46 pairs of sister chromatids. During mitosis, the sister chromatids separate into two identical daughter nuclei, each having 46 chromosomes.
What happens when mitosis is done?
The stages are as follows: Interphase, prophase, metaphase, anaphase, telophase, and cytokinesis. A cell will normally spend the majority of its time in interphase (during this time, the cell prepares itself for cell division. Interphase has three phases: G1, S, G2. Growth, synthesis, and growth 2. As already stated, this is all in preparation for cell division. In prophase, the chromatids (genetic material) begin to condense and the centrosomes create spindle fibers. During metaphase, the chromosomes align themselves on the metaphase plate. During metaphase, the chromosomes are pulled apart. During telophase, the separated chromosomes begin to form two new nuclei and the nuclear membrane begins to form. Cytokinesis is the process during which a cleavage furrow develops along the metaphase plate and pinches the two nuclei apart thus creating two separate cells.

Distribution of chromosomes into separate and equal nuclei?
Mitosis
Single sister chromatids are found in cells at mitotic?
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.
What HAPPENS DUR?
Mitosis is the division of the chromosomes in the nuclei. There are 5 stages in mitosis. Interphase, prophase, metaphase, anaphase, and telophase.
How many chromosomes are there in each stage of mitosis?
In humans, during interphase, before DNA replication, there are 46 chromosomes. After DNA replication, there are 92 chromosomes (4 sets of 23). During prophase, metaphase, and anaphase, there are 92 chromosomes. During anaphase, the 4 sets of chromosomes separate into 2 sets of 23 and move to opposite poles. There are still 92 chromosomes in the cell. During telophase each of the 2 sets of 23 chromosomes separate to opposite poles and a new nuclear membrane forms around each of the 2 sets, forming two new identical nuclei, each with 2 sets of 23 chromosomes. Once the cell divides in the process of cytokinesis, there will be two new identical daughter nuclei in two new daughter cells, each containing 2 sets of 23 chromosomes for a total of 46, and each of the two daughter cells will enter into interphase.
What does a nucleus do in a mitosis of a single cell?
During the first stage of mitosis, prophase, the nucleus and nucleolus disappear. Mitosis then proceeds into metaphase and anaphase. Then during telophase, the nuclei reappear in the two cells and finally the cells split apart from each other by a process known as cytokinesis.
What happens durring mitosis?
Mitosis is the division of the chromosomes in the nuclei. There are 5 stages in mitosis. Interphase, prophase, metaphase, anaphase, and telophase.
What are 8 phases of meosis?
Metaphase I In metaphase I, the tetrads get aligned at the center of the cell, at the equatorial plane. Anaphase I The homologous chromosomes separate during this stage. Telophase I The chromosomes continue to migrate towards the poles. Both the poles have haploid number of chromosomes. Prophase II The nuclei and nuclear membrane are separated. The chromosomes start moving towards the equatorial plane. Metaphase II The chromosomes are aligned at the equatorial plane prior to separation. Anaphase II The sister chromatids held at the centromere are separated by the spindle fibers. Chromatid pairs begin to move towards the poles. Telophase II Four nuclei (two each in a daughter cell) are formed by the process of cytokinesis. Each of the four nuclei develops a nuclear envelope. Four daughter cells or gametes are formed.
What is the Distribution of chromosomes into separate and equal nuclei is referred to as?
The answer is mitosis- The orderly division of the nucleus of a cell that ensures that each new nucleus has the same number and kind of chromosomes as the original nucleus. The process includes the replication of chromosomes and the distribution of the two sets of chromosomes into two separate and equal nuclei.
