Explain how the following terms are related to one another dna centromere chromosome chromatid?
DNA is bundled up into a chromossome with could be one or two chromatids depending on where the cell is in its cell cycle (two chromatids give the chromossome that X look). Both chromatids are bound together by a centromere.
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.
Chromatids are held together by a?
They are held together, or conjoined, at their centromeres. These quite small regions of the chromosome pairs contain a specific set or 'mix' of nucleotides that are most Happy when being 'confined' in close-quarters. Chromatin is another matter.
What are chromosome pairs attached to?
Pairs of chromosomes are not attached. Before mitosis chromosomes replicate themselves, these twin identical chromosomes are attached at the centromere. before cell division the cell has 46 chromosomes (23 pairs) but has 2 copies of each individual chromosome called chromatids,(making a total of 92 chromosones, 46 for each daughter cell) which are joined at the centromere giving the characteristic X shape. Pairs are not joined, chromatids are.
The centromere is a region in which?
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.

What is difference between chromosome and chromatids?
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. They are known as sister chromatids. Once the paired sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.

How are chromatid and a duplicated chromosome are related?
Chromosomes and chromatids are related in that one is the duplicate of another. A chromatid comes about when chromosomes are duplicated. It holds replicated DNA of every single chromosome that is joined.
The chromatids detach from one another and become visibly separate chromosomes during?
This process occurs during anaphase of mitosis or meiosis. As the sister chromatids are pulled towards opposite poles of the cell by the spindle fibers, they become individual chromosomes. This separation ensures that each daughter cell receives a complete set of genetic material.
What is the relationship between chromaids and chromosomes?
Normally a cells chromosomes are single strands - a bit like a pice of string. Just prior to cell division, a chromosome replicates (=makes another copy of itself) and these two copies are joined together at a point called the centromere. Each copy is now called a chromatid and being joined at the centromere make the familiar "X" shape, with each copy (chromatid) forming a side of the X and will have exactly the same sequence of genes down its length as the other chromatid (they are copies!). In cell division the copies (chromatids) will be pulled apart (X becomes > <) to become chromosomes in their own right.
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."

What is o kitetochore?
A kinetochore is another name for a centromere. A centromere is the protein structure of a cell involved in cell division.
What happens to sister chromatids in meiosis?
They are separated and pulled to the opposite ends, or poles.
