What is one of the two strands of a chromosome that become visible during meiosis or mitosis?
One of the two strands of a chromosome that becomes visible during meiosis or mitosis is known as the chromatid. Each chromatid is an exact copy of the other, formed during DNA replication in the interphase preceding cell division.
What is each chromatid called after ther centromeres divide and the sister chromatids separate during mitosis?
After the centromeres divide and the sister chromatids separate during mitosis, each chromatid is referred to as a daughter chromosome. At this stage, the daughter chromosomes are distinct and no longer considered sister chromatids, as they are now individual chromosomes that will move to opposite poles of the cell during anaphase.
What is the difference between a chromatid and a centromere?
The centromere is the region of the chromosome that holds the two sister chromatids together during mitosis. The chromatid is one of the two strands of chromosomes that become visible during mitosis or meiosis.
Holds sister chromatids together?
The primary structure that holds sister chromatids together is the centromere. This region of DNA is responsible for ensuring that each daughter cell receives one copy of each chromatid during cell division. Additionally, proteins known as cohesins also play a role in maintaining the physical connection between sister chromatids until they are separated during mitosis or meiosis.
What separates sister cells during mitosis?
During mitosis, sister chromatids are separated by the spindle fibers attached to the centromeres of each chromatid. This process ensures that each daughter cell receives an identical set of chromosomes as the parent cell divides.

What are the Two strands of chromosome that become visible during meiosis or mitosis?
chromatid
At what stage does sister chromatid separation occur by mitosis and meiosis?
Sister chromatid separation occurs during anaphase of mitosis and anaphase II of meiosis. In mitosis, sister chromatids are separated to opposite poles of the cell, while in meiosis II, sister chromatids are separated to produce four haploid daughter cells.
What is A strand of replicated DNA formed during prophase called?
A strand of replicated DNA formed during prophase is called a sister chromatid. Sister chromatids are identical copies of each other produced during DNA replication and are held together by a structure called the centromere.
What is the difference between a chromatid and a centromere?
The centromere is the region of the chromosome that holds the two sister chromatids together during mitosis. The chromatid is one of the two strands of chromosomes that become visible during mitosis or meiosis.

What is cytokinesis phase?
Cytokinesis is completed shortly after the chromatid separation. This process occurs during the anaphase stage of mitosis in a cell's life cycle.
What separates sister cells during mitosis?
During mitosis, sister chromatids are separated by the spindle fibers attached to the centromeres of each chromatid. This process ensures that each daughter cell receives an identical set of chromosomes as the parent cell divides.
What structure holds two strands of DNA together after replication until metaphase of mitosis?
The structure that holds two strands of DNA together after replication until metaphase of mitosis is the centromere. The centromere is a region of the chromosome where the two sister chromatids are held together and is essential for proper chromosomal segregation during cell division.
What region of the chromosome serves as the attachment site for microtubules during Cell division?
The kinetochore is the region of the chromosome that serves as the attachment site for microtubules during cell division. It is a protein structure that forms on the centromere of a chromatid. Kinetochore microtubules connect the chromatids to the mitotic spindle to aid in the separation of chromosomes during mitosis.
What structure will the chromatin become in mitosis?
The chromatin in the cell becomes chromosomes in prophase, the first stage of mitosis. The chromatin coils tightly together to form into separate chromosome strands during this phase.
How does a single pair of sister chromatids differ from a single unduplicated chromozone?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
