centromere
The chromatids of a chromosome are attached at a point called the centromere. The centromere is a region where the two chromatids are closely aligned and hold together until they separate during cell division.

Sister chromatids in a chromosome are attached by a structure called the centromere. The centromere is a region where the two sister chromatids are held together until they separate during cell division.

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.
No, sister chromatids are separated during anaphase of meiosis I. In prophase II of meiosis, each chromatid (now called a chromosome) pairs with its homologous chromosome, but they are not connected as sister chromatids.
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.
The point of attatchment between two chromatids is called the centromere. When two chromatids are connected, it is called a chromosome which is essential in DNA replication, or, mitosis.
A duplicated chromosome, with two identical portions attached by their centromere, is referred to as a sister chromatid. Sister chromatids are produced during DNA replication and are important for ensuring accurate distribution of genetic material during cell division.
