What is sister chromatin?
Sister chromatids are two identical copies of a single replicated chromosome that are joined by a centromere. During cell division, sister chromatids are separated and move to opposite poles of the cell to ensure each daughter cell receives an exact copy of the genetic material.
Does sister chromatids split during prophase?
Sister chromatids do not split during prophase. They consist of two identical copies of a chromosome held together by a centromere. Sister chromatids separate and move to opposite poles during the later stages of cell division.
What is centromere and what is its role in mitosis?
The centromere is a region of a chromosome where two sister chromatids are joined together and serves as the attachment point for spindle fibers during cell division. Its primary role in mitosis is to ensure accurate segregation of chromosomes by facilitating the proper alignment and movement of chromatids to opposite poles of the dividing cell. This ensures that each daughter cell receives an identical set of chromosomes, maintaining genetic stability.
Which specific structure must separate during anaphase in order for sister chromatids to begin moving toward opposite poles?
During anaphase, the centromere must separate for sister chromatids to start moving towards opposite poles. This separation allows each chromatid to be pulled to the poles by the spindle fibers attached to the centromere.
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 chromatids identical halves of a duplicated parent chromosome formed during the prophase stage of mitosis the halves are held together by a centromere?
The chromatids are the identical halves of a duplicated chromosome that are held together by a centromere. During the prophase stage of mitosis, the chromatids condense and become visible as distinct structures. These chromatids will eventually separate during anaphase and move to opposite poles of the cell.
Does sister chromatids split during prophase?
Sister chromatids do not split during prophase. They consist of two identical copies of a chromosome held together by a centromere. Sister chromatids separate and move to opposite poles during the later stages of cell division.
Describe the chromatids that make up a chromosome when a cell is ready to divide?
Chromatids are identical copies of DNA that are joined together at the centromere to form a chromosome. Each chromatid carries genetic information necessary for cell division. When a cell is ready to divide, the chromatids separate and are pulled to opposite ends of the cell.

In what phase of mitosis do the sister chromatids move to opposite poles of the cell?
In the third stage, anaphase, the sister chromatids ofeach replicated chromosome begin to separate.Fibers pull the centromere apart and chromatidsmove away from each other, toward opposite ends of thecell.
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 are the two halves of a double chromosome structure called?
The two halves of a chromosome are called chromatids, or, more fully, sister-chromatids.Each sister-chromatid contains one molecule of DNA. The two DNA molecules of one chromosome are, barring occasional copying errors, genetically identical, because they were formed from the same original DNA molecule at the most recent replication.
How many sister chromatids present during anaphase of mitosis?
There are a total of four sister chromatids present during anaphase of mitosis. Each replicated chromosome consists of two sister chromatids that are held together by a centromere. During anaphase, these sister chromatids separate and are pulled to 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.
What phase do centromeres break?
Centromere splitting is something that happens to the Chromosomes during the M Phase (Mitosis) of cell division. During Anaphase (a phase in the M Phase), the centrioles that have sent out spindle fibers and are at opposite poles just tug at the centromere of the Chromosome, causing the centromere to split. Anaphase is basically centromere splitting, where the spindle fibers from the centrioles split the chromosome in half at the centromere.
