Sister chromatids are held together at a region of highly condensed DNA called the centromere. The centromere region is very important during the process of cell division where chromosomes have to segregate into daughter cells. In addition, chromosomes are classified into different groups based on the position of the centromere
Sister chromatids are held together by a structure called the centromere, which helps ensure the accurate distribution of genetic material during cell division. The centromere serves as a site for the attachment of microtubules that help segregate the sister chromatids into separate daughter cells.

The replicas of chromosomes that form during prophase are called what?
During prophase, a chromosome is composed of tightly coiled DNA and protein molecules. Each chromosome exists as a pair of identical sister chromatids which are held together at the centromere.
What phase do sister chromatids form?
Sister chromatids form during the S phase of the cell cycle, when DNA replication takes place. Each replicated chromosome consists of two sister chromatids held together by a centromere.
After replication each chromosome harbors what?
After replication, each chromosome harbors two sister chromatids, which are identical copies of the original chromosome. The sister chromatids are held together at the centromere and will later separate during cell division.
What is the structure at the center of the chromosomes where sister chromatids are attached?
The structure at the center of the chromosomes where sister chromatids are attached is called the centromere. It serves as a point of attachment for the spindle fibers during cell division and helps in the proper segregation of genetic material to daughter cells.
When chromosome become visible at the beginning of cell division what does each chromosome consist of?
Each chromosome consists of two identical sister chromatids that are held together by a centromere. These sister chromatids contain the genetic information needed for the cell to function and are divided evenly between the two daughter cells during cell division.
During prophase what structures are held together by the centromeres?
The sister chromatids are held together by the centromeres. Each chromosome is made up of two sister chromatids.
What are the sister chromatids in a chromosome attached by?
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.
Where are chromatids held together?
Chromatids are held together at the center by a structure called the centromere. This region contains specific DNA sequences to which proteins bind to physically connect the two sister chromatids. The centromere plays a critical role in ensuring accurate segregation of chromatids during cell division.
The replicas of chromosomes that form during prophase are called what?
During prophase, a chromosome is composed of tightly coiled DNA and protein molecules. Each chromosome exists as a pair of identical sister chromatids which are held together at the centromere.
Copies of chromosomes liked together at their centromeres at the beginning of meiosis are called what kid of chromatid?
At the beginning of meiosis, copies of chromosomes linked together at their centromeres are called sister chromatids. These sister chromatids are duplicated copies of a single chromosome and are held together by proteins called cohesins.
What phase do sister chromatids form?
Sister chromatids form during the S phase of the cell cycle, when DNA replication takes place. Each replicated chromosome consists of two sister chromatids held together by a centromere.
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.
After replication each chromosome harbors what?
After replication, each chromosome harbors two sister chromatids, which are identical copies of the original chromosome. The sister chromatids are held together at the centromere and will later separate during cell division.
What is the structure at the center of the chromosomes where sister chromatids are attached?
The structure at the center of the chromosomes where sister chromatids are attached is called the centromere. It serves as a point of attachment for the spindle fibers during cell division and helps in the proper segregation of genetic material to daughter cells.
What structures hold the sister chromatids together?
Sister chromatids are held together by a protein complex called cohesin, which forms a ring-like structure around the two chromatids. Cohesin binds to specific DNA sequences on the chromatids and helps in ensuring that they are properly aligned and segregated during cell division.
When chromosome become visible at the beginning of cell division what does each chromosome consist of?
Each chromosome consists of two identical sister chromatids that are held together by a centromere. These sister chromatids contain the genetic information needed for the cell to function and are divided evenly between the two daughter cells during cell division.
During the s phase chromosomes are converted to what form?
During the S phase of the cell cycle, chromosomes are replicated to form sister chromatids. Sister chromatids are two identical copies of a single replicated chromosome that are held together by a centromere.
