The region of a chromosome where two sister chromatids attach is called the centromere. It appears as a constricted area on the chromosome, serving as a site for protein binding and attachment of spindle fibers during cell division. The centromere plays a crucial role in ensuring proper segregation of chromosomes during mitosis and meiosis.

Specify the location and function of the centromere?
The centromere is a region of a chromosome that is typically located near the center. Its primary function is to facilitate the attachment and segregation of sister 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.
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 center of a chromosomes called?
The center of a chromosome is called the centromere. It is a region where two sister chromatids are closely attached and where spindle fibers attach during cell division to pull the chromatids apart.
Are sister chromatids still attached in prophase 2 of meiosis?
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.
What joins arms together and is the place where spindle fibers attach to each chromosome?
A centromere is the region of a chromosome where spindle fibers attach during cell division. It is responsible for joining the two sister chromatids together.
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.
Each chromosome consists of 2 what?
Each chromosome consists of two sister chromatids, which are identical copies of the chromosome connected at a region called the centromere. During cell division, the sister chromatids separate and each is passed on to a daughter cell.
What is the small section of a chromosome where sister chromatids attach to each other?
The small section of a chromosome where sister chromatids attach to each other is called the centromere. It plays a crucial role in ensuring accurate segregation of genetic material during cell division.
The region of the chromosome that holds the two sister chromatids together during mitosis?
Centromere
What is the structure called that holds two chromatids together?
The structure that holds two chromatids together is called a centromere. It is a region of the chromosome where the two sister chromatids are attached and where the microtubules of the spindle fibers attach during cell division.
What is the region of chromosomes where paired chromosomes are joined?
The centromere is the part of the chromosome where sister chromatids are joined together.
Specify the location and function of the centromere?
The centromere is a region of a chromosome that is typically located near the center. Its primary function is to facilitate the attachment and segregation of sister chromatids during cell division.
What is the sides of a chromosome called after they are in the structure?
After condensation, the sides of a chromosome are called sister chromatids. Sister chromatids are exact copies of each other, joined together by a region called 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.
Why does a chromosome has two sister chromatids?
because it can
