When DNA is replicated the copied sister chromatids remain attached to what strcture?
The copied sister chromatids remain attached to the centromere, which is a specialized region of the chromosome where the two chromatids are joined. This attachment is crucial for ensuring that each daughter cell receives one copy of each chromatid during cell division.
What chromatids are attached at the centromere?
Sister chromatids are the chromatids that are attached at the centromere. Sister chromatids are two identical copies of a chromosome produced during DNA replication, and they remain attached until they are separated during cell division.
2. What are sister chromatids When do the separate?
In anaphase I the sister chromatids remain attached, while in anaphase II the sister chromatids separate.
The centromere is a region in which?
The centromere is a region in a chromosome where the two sister chromatids are held together. It is responsible for ensuring proper chromosome segregation during cell division. It also plays a key role in attaching chromosomes to the mitotic spindle fibers.
Chromosomes during prophase are made up of two identical strands What are these strands called?
The two identical strands of a chromosome are called chromatids. DNA replication occurs in the interphase stage of the cell cycle.
When DNA has replicated the copied sister chromatin's remain attached to what structure?
After DNA replication, the copied sister chromatids remain attached at a region called the centromere. The centromere holds the sister chromatids together until they are separated during cell division. This attachment is crucial for proper chromosome segregation during mitosis and meiosis.

What chromatids are attached at the centromere?
Sister chromatids are the chromatids that are attached at the centromere. Sister chromatids are two identical copies of a chromosome produced during DNA replication, and they remain attached until they are separated during cell division.
Are sister chromatids are held together by a structure called synapse?
No, sister chromatids are held together by a structure called the centromere, not synapse. The term "synapse" refers to the junction between two neurons or the pairing of homologous chromosomes during meiosis, not the connection of sister chromatids. During cell division, sister chromatids remain attached at the centromere until they are separated during mitosis or meiosis.
2. What are sister chromatids When do the separate?
In anaphase I the sister chromatids remain attached, while in anaphase II the sister chromatids separate.
Are sister chromatids identical before crossing over occurs?
Yes they are attached at the centromere and remain identicle until crossing over occurs in prophase 1 of meosis

The centromere is a region in a chromosome where the two sister chromatids are held together. It is responsible for ensuring proper chromosome segregation during cell division. It also plays a key role in attaching chromosomes to the mitotic spindle fibers.
What process chromomes duplicate and the copies remain attached to each other?
Chromosomes duplicate during the cell cycle's S phase, resulting in two identical sister chromatids for each chromosome. These sister chromatids remain attached at a region called the centromere until the cell enters mitosis or meiosis, where they are eventually separated into daughter cells. This attachment ensures accurate distribution of genetic material during cell division.
Chromosomes during prophase are made up of two identical strands What are these strands called?
The two identical strands of a chromosome are called chromatids. DNA replication occurs in the interphase stage of the cell cycle.
During what stage the centromere does not divide?
The centromere does not divide during the anaphase of meiosis I. In this stage, homologous chromosomes separate and move to opposite poles, but the sister chromatids remain attached at their centromeres. Division of the centromere occurs later, during anaphase II of meiosis when the sister chromatids finally separate.
Paired chromatin that are like copies of DNA?
Paired chromatin that are like copies of DNA refer to sister chromatids. Sister chromatids are replicated during the S phase of the cell cycle and remain attached at the centromere until they are separated during cell division. Each sister chromatid is an identical copy of the original DNA molecule.
What is centremere?
The point along the length of homologous chromatids where they remain held together to form a chromosome.
