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.

What else can I help you with?
What is different between a chromosome and a chromatid?
Chromosome need 2 chromatids but a chromatid is only half of a chromosome
What is the point of attachment between two chromatids?
The point of attatchment between two chromatids is called the centromere. When two chromatids are connected, it is called a chromosome which is essential in DNA replication, or, mitosis.
How many chromatids are involved in crossing over of a homologous pair of chromosomes?
Crossing over involves the exchange of genetic material between homologous chromosomes during meiosis. Each homologous pair consists of four chromatids (two from each chromosome), and crossing over occurs between a pair of chromatids from each homologous chromosome. This results in the exchange of genetic material between the chromatids.
How many chromatids does a chromosome typically have when a karyotype is taken?
When a karyotype is taken, a chromosome typically has two chromatids.
How many chromatids have one chromosome?
Two (2). Before DNA replication, each chromosome is composed of a single chromatid. After replication, but before separation of the chromatids during anaphase, this is true.
There are 4 chromatids in a?
A chromatid is one half of a duplicated chromosome, so typically there are 2 chromatids in a chromosome.
Do sister chromatids have the same alleles within a chromosome?
Yes, sister chromatids have the same alleles within a chromosome.
What is the difference between sister and non sister chromatids?
Sister chromatids are those replicated from the same chromosome whereas non-sister chromatids may be found in meiosis (particularly metaphase II) where paternal and maternal chromatids line up and eventually separate at the metaphase plate.
What is the term for the two sets of chromatids?
A chromosome pair, as in a pair of Chromosome 15, or a pair of Chromosome 5. Others have said Tetrad - Pls stand-by.
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
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.
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.
