In what stage do chromatids separate?
Chromatids separate during the anaphase stage of mitosis. This is when sister chromatids are pulled to opposite poles of the cell by the spindle fibers, leading to the formation of two identical daughter chromosomes.
What happens during mitotic division?
During mitotic division, a cell undergoes a series of stages such as prophase, metaphase, anaphase, and telophase, leading to the formation of two identical daughter cells. Chromosomes condense, align in the center of the cell, separate, and then the cell divides into two. This process ensures that each daughter cell receives an identical copy of the genetic material.
Single cells split into 2 cells?
Mitosis is the process in which a cell divides and makes two daughter cells that are genetically identical to it. Chromosomes in the nucleus of the original cell separate and make identical sets of chromosomes, each of which is in its own nucleus.
A cell shows alignment of chromosomes along the Equatorial plate. what will happen next?
When chromosomes align along the equatorial plate during metaphase, the next step will be anaphase. During anaphase, the spindle fibers will pull the sister chromatids apart towards opposite poles of the cell. This ensures that each daughter cell will receive an identical set of chromosomes when the cell divides. Following anaphase, the cell will enter telophase, where the chromosomes will de-condense and nuclear envelopes will reform around each set of chromosomes.
What happens during anaphase 1and 2?
Anaphase 1: 1. Breakdown of proteins responsible for sister chromatid cohesion along chromatid arms allows homologs to separate. 2. The homologs move toward opposite poles, guided by the spindle apparatus. 3. Sister chromatid cohesion persists at the centromere, causing chromatids to move as a unit towards the same pole. At anaphase 1 of meiosis, the replicated chromosomes of each homologous pair move toward opposite poles, but the sister chromatids of each replicated chromosome remain attached. In anaphase of mitosis, by contrast, sister chromatids separate. Reference Cambell et al. Biology (8th Ed) 2008. Benjamin Cummings. pg 254-257
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.
How is anaphase I of meiosis different than anaphase of mitosis?
In anaphase for both types of cell division, the centromeres of each chromosome separates and the spindle fibers pull apart the sister chromosomes. In mitosis, this is the shortest phase of cell division.However, the differences between mitosis and meiosis are different. Because meiosis is when chromosomes are "mixed and matched" in order to make new different combinations, the strands are only mixed up so when they split, they have new genes at their ends. Because mitosis is when chromosomes are duplicated, or cloned, and are copies of each other, when they split, the new cell is the exact same copy as the original.
Summarize what happens to chromosomes during the stage of the cell cycle in which the nucleus divides Include the terms prophase metaphase anaphase and telophase?
Prophase: Chromosomes condense into visual forms and nuclear envelope breaks down. Metaphase: Chromosomes pair and line up along metaphase plate(midline) and also attatch to mitotic spindles at centromere. Anaphase: Mitotic spindles attached to chromosomes pull half of the chromosomes to each side of cell. Telophase: Nuclear envelope begins to reform. animal cells: Cleavage in cell occurs which divides cell into two. plant cells: Cell wall forms in the middle of cell to separate the cell.
How does mitosis work?
Mitosis is the process in which a cell divides to produce two genetically identical daughter cells. It involves stages such as prophase, metaphase, anaphase, and telophase. During mitosis, the cell's chromosomes are copied and then separated into two identical sets before the cell divides.

Stage of the cell cycle during which the cells nucleus divides?
The stage of the cell cycle during which the cell's nucleus divides is called mitosis. Mitosis is divided into several phases: prophase, metaphase, anaphase, and telophase. During this process, the replicated chromosomes are separated into two nuclei, ensuring that each daughter cell receives an identical set of chromosomes. Following mitosis, the cell typically undergoes cytokinesis, which divides the cytoplasm and completes cell division.
Summarize the events that occur during mitosis and cytokinesis?
During mitosis, the cell's nucleus divides into two daughter nuclei with identical DNA copies. This process involves stages such as prophase, metaphase, anaphase, and telophase. Cytokinesis follows mitosis and involves the division of the cell's cytoplasm to create two separate daughter cells.
