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.

What else can I help you with?
When do the chromosomes separate in mitosis?
Sister chromatids separate during Anaphase II of meiosis.*They are pulled apart and then start moving to opposite sides of the cell.
Which phase do sister chromatids separate?
well in meiosis one the chromosomes form a tetrad and do a cross overso i say its in anaphase 2
What phase of the cell cycle do centromeres divide?
It depends on whether you're talking about mitosis or meiosis. In mitosis, it is during anaphase. In meiosis, where the cell divides twice, centromeres aren't separated until anaphase II. In anaphase I, chromosomes are arranged as tetrads, and these tetrads are pulled apart to create two daughter cells, each with a full copy of the original cells' diploid chromosome.
What happens during synapsas in meiosis?
The purpose of synapsis in meiosis is to increase genetic variability. It does this as the homolog pairs match up, which means there are 4 chromosomes of like, but possibly unique, DNA data in the grouping. This allows the cell. as it proceeds through Anaphase 1 and Anaphase 2 to separate the individual chromosomes first into 2 pairs then as individuals, which inturn adds to the variability as 1 chromosome goes to each daughter cell. .
How many chromosomes does new cells have at the end of the cycle?
Anaphase 1: Before Meiosis begins, each chromosome is duplicated, like in Mitosis. When the cell is ready for meiosis, each duplicated chromosome is visible under the microscope as two Chromatids. Anaphase 2:The two cells formed during Meioses 1 now begin Meiosis 2. The chromatids of each duplicated chromosome will be separated during this division. (Anaphase also means Meiosis. Meiosis 1 and Meiosis 2 for instance. i hoped this helped!)
Chromatins separate during?
Chromatids separate during cell division ie anaphase of mitosis and anaphase 2 of meiosis.
When do the chromosomes separate in mitosis?
Sister chromatids separate during Anaphase II of meiosis.*They are pulled apart and then start moving to opposite sides of the cell.
During meiosis the chromatids become daughter chromosomes during which stage?
The chromatids become daughter chromosomes during the anaphase stage of meiosis, specifically during anaphase II in the case of meiosis II. In these stages, the chromatids are separated and move towards opposite poles of the cell, becoming individual chromosomes.
During what stage are sister chromatids separated and moved to opposite ends of the cell?
Anaphase. My old biology teacher used to say you could remember it because the chromatids look like hands of bananas when they're being pulled apart. Banana sounds sort of like the 'ana' bit of anaphase if you pronounce it funny.
What happens when a cell under go mitosis?
Mitosis is broken up into 4 phases, Prophase, Metophase, Anaphase, and Telophase. During these phases the DNA, which was replicated during Interphase, split and 2 new cells are formed.
Do centromeres divide at anaphase you or II?
anaphase 2
What happens to centromere in anaphase 1?
In anaphase 1 of meiosis, the centromeres divide, separating the pairs of homologous chromosomes. Each chromosome is then pulled toward opposite poles of the cell by the spindle fibers attached to the centromeres. This results in the distribution of one member of each homologous pair to each daughter cell.
What is the correct order for the sequence of meiosis?
Interphase Prophase 1 Metaphase 1 Anaphase 1 Telophase 1 Cytokinesis 1 Prophase 2 Metaphase 2 Anaphase 2 Telophase 2 Cytokinesis 2
Which phase do sister chromatids separate?
well in meiosis one the chromosomes form a tetrad and do a cross overso i say its in anaphase 2
What is the difference between anaphase 1 and anaphase 2 in meiosis?
Hello, Anaphase 1 and 2 are both part of the process of meiosis, the division of sex cells, and they are both phases where chromosomes are being pulled apart by the centrioles. However, in anaphase one the chromosomes are lined up in homologous pairs, meaning that there are two chromosomes side by side, so when the centrioles pull they are separating two unconnected chromosomes. In anaphase two the chromosomes are lined up in single file. So the centrioles are pulling one chromosome apart. It eventually breaks the link at the centromere of the chromosome and results in two sister chromatids. Hope this is clear enough to understand!
