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

What is the structure at the center of the chromosomes where sister chromatids are attached?
When sister chromatids are joined together they are held together by proteins, which make up the centromere. The two chromatids together make up a chromosome.
What structure holds the sister chromatids to the spindle fibers?
Sister chromatids are held together by centromere and are attached to the spindle fibres by kinetochores 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.
When chromosome become visible at the beginning of cell division what does each chromosome consist of?
each chromosome consists of two identical "sister" chromatids
When a double helix DNA is replicated two complete helices are formed together these helices are called sister?
Sister chromatids - two copies of the same DNA joined at the centromere.
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 is the structure at the center of the chromosomes where sister chromatids are attached?
When sister chromatids are joined together they are held together by proteins, which make up the centromere. The two chromatids together make up a chromosome.
Where are chromatids held together?
the centromere is where the sister chromatids interlock in the middle but the kinetochore holds them together.
What structure holds the sister chromatids to the spindle fibers?
Sister chromatids are held together by centromere and are attached to the spindle fibres by kinetochores during cell division.
Holds sister chromatids together?
the centromere
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 is the name of the structure that connects the sister chromatids?
The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
What structure are chromatids held together by?
Centromere
What are matching chromatids held together by?
A centromere.
What structure is formed by two sister chromatids being held together by a centromere?
A bivalent.Sister chromatids are normally joined at the centromere. When homologous chromosomes pair, the two sister chromatids of one chromosome join with the two sister chromatids of the other chromosome. So it is really the joining of non-sister chromatids that is special.The word "bivalent" refers to the temporary combining of the two chromosomes (four chromatids). The bivalent forms in prophase I of meiosis, and is split in anaphase I.
When chromosome become visible at the beginning of cell division what does each chromosome consist of?
each chromosome consists of two identical "sister" chromatids
When all the genes of a chromosome have duplicated but are still attached the strutures that are formed are called?
When all the genes of a chromosome have duplicated but are still attached, the structures that are formed are called sister chromatids. Sister chromatids are identical copies of each other, and they are held together at a specialized region called the centromere.
