Cohesins join sister chromatids during the S phase of the cell cycle. This is when DNA replication occurs, resulting in the formation of identical sister chromatids bound together by cohesin proteins.

What can one half of a duplicated chromosome be referred as?
A chromatid is one-half of two identical copies of a replicated chromosome. During cell division, the identical copies are joined together at the region of the chromosome called the centromere.Joined chromatids are known as sister chromatids. Once the joined sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.Chromatids are formed from chromatin fibers.Bailey, Regina. "Chromatid." ThoughtCo, Apr. 17, 2017.
How are chromatid and a duplicated chromosome are related?
A chromatid is one of the two identical copies of a chromosome that are joined at the centromere. When a chromosome is duplicated during DNA replication, each half of the chromosome becomes a chromatid. Therefore, a duplicated chromosome consists of two sister chromatids.
How many sister chromatids are there in a duplicated chromosomes?
There are two sister chromatids in a duplicated chromosome. Each sister chromatid is an identical copy resulting from DNA replication during the S phase of the cell cycle.
When a chromosome has been duplicated it consists of two identical pieces attached together called?
A chromosome is a long, highly coiled strand of DNA. When the cell is undergoing replication, the DNA strand will replicate to form two identical copies, one copy goes to each daughter cell. However, a human cell consists of 23 paired homologus chromosomes to give 46 chromosomes in total.
What are the two halves of a double chromosome structure called?
The two halves of a chromosome are called chromatids, or, more fully, sister-chromatids.Each sister-chromatid contains one molecule of DNA. The two DNA molecules of one chromosome are, barring occasional copying errors, genetically identical, because they were formed from the same original DNA molecule at the most recent replication.
One half of a duplicated chromosome?
A duplicated chromosome consists of two identical sister chromatids joined at the centromere. Therefore, one half of a duplicated chromosome refers to one of these sister chromatids, which contains a copy of the genetic material from the original chromosome.
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
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 is a chromosome has been duplicated the two indentical portions that are attached by their centromere?
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.
What can one half of a duplicated chromosome be referred as?
A chromatid is one-half of two identical copies of a replicated chromosome. During cell division, the identical copies are joined together at the region of the chromosome called the centromere.Joined chromatids are known as 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.
How are chromatid and a duplicated chromosome are related?
A chromatid is one of the two identical copies of a chromosome that are joined at the centromere. When a chromosome is duplicated during DNA replication, each half of the chromosome becomes a chromatid. Therefore, a duplicated chromosome consists of two sister chromatids.
How many sister chromatids are there in a duplicated chromosomes?
There are two sister chromatids in a duplicated chromosome. Each sister chromatid is an identical copy resulting from DNA replication during the S phase of the cell cycle.
A duplicated chromosome consists of two?
Two sister-chromatids.Each chromatid consists of a molecule of DNA together with associated proteins. There are two DNA molecules (sister-chromatids) following the replication of DNA midway through the preceding interphase. The sister-chromatids are therefore genetically identical.chromatidschromatidsThe two identical joined chromosomes before cell division begins is called sister chromatids.
Are joined strands of duplicated genetic material?
Chromosomes and sister chromatids are joined strands of duplicated genetic material. A chromatid is one copy of a duplicated chromosome which, before replication, is composed of one DNA molecule.
When a chromosome has been duplicated it consists of two identical pieces attached together called?
A chromosome is a long, highly coiled strand of DNA. When the cell is undergoing replication, the DNA strand will replicate to form two identical copies, one copy goes to each daughter cell. However, a human cell consists of 23 paired homologus chromosomes to give 46 chromosomes in total.
