What structure is formed by two sister chromatids being held together by a centromere?
A bivalent.Sister chromatids are normally joined at the centromere. When homologous chromosomes pair, the two sister chromatids of one chromosome join with the two sister chromatids of the other chromosome. So it is really the joining of non-sister chromatids that is special.The word "bivalent" refers to the temporary combining of the two chromosomes (four chromatids). The bivalent forms in prophase I of meiosis, and is split in anaphase I.
What separates during meiosis 2?
In Meiosis, Anaphase 2 sister chromatids (individual strands) separate and one of each duplicate goes to each side of the cell.
During of meiosis sister chromatids are separated and pulled to opposite ends of the cell.?
During meiosis, sister chromatids are separated during the second meiotic division, specifically in anaphase II. At this stage, the centromeres that hold the sister chromatids together split, allowing the chromatids to move to opposite poles of the cell. This separation ensures that each resulting gamete contains only one copy of each chromosome, contributing to genetic diversity. Ultimately, this process leads to the formation of four haploid cells from one diploid cell.
In which stage of mitosis do the paired chromatids break part?
During anaphase in mitosis, the paired chromatids break apart and move to opposite ends of the cell.
When do chromosome duplicate themselves during mitosis?
Chromosomes duplicate during the S phase of interphase, which occurs before mitosis. Each chromosome replicates to form two identical sister chromatids that are held together at the centromere. These sister chromatids are then separated and pulled to opposite poles of the cell during mitosis.
What happen in each phase of mitosis?
well there are 4 phases and they are telophase, anaphase, metaphase, and the prophase. telophase is the last phase where everything is finished and there are 2 nucleuses. Anaphase is when the sister chromatids or x is split into different sides. Metaphase is when all the sister chromatids or x are lined up in the middle. prophase is when everthing is about to start.
How do centromeres that join sister chromatids split during cell division?
During cell division, centromeres that join sister chromatids split by a process called mitosis. This involves the separation of the sister chromatids, with each chromatid moving to opposite ends of the cell. This ensures that each new cell receives a complete set of chromosomes.

Stage of mitosis where chromosomes split apart?
Anaphase is the stage of mitosis where chromosomes split apart. During anaphase, the sister chromatids are pulled towards opposite poles of the cell by the spindle fibers. This separation ensures that each resulting daughter cell receives a full set of chromosomes.
What are the two copies of a chromosome called after they split?
Sister chromatids
What stage of mitosis does the sister chromatids spilt?
Anaphase Source: My book on page 169 "As you may have guessed, this is a parting of sisters. the sister chromatids are pulled apart, each now becoming full fledged chromosome.
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.
Which phase of the cell cycle does the centromeres split?
The centromeres split during the anaphase stage of mitosis. This is when the paired sister chromatids are pulled towards opposite poles of the cell by the spindle fibers.

What is the relationship between chromosomes and chromatids?
Chromosomes are the condensed and replicated form of DNA. The two identical halves of the chromosomes are known as sister chromatids. Before division, while the chromatids are still attached, they form one chromosome. However, when anaphase (i.e the stage when chromosomes split) starts and they are separated, the two chromatids on the opposite poles of the cell become complete chromosomes.
