During S of interphase.

A chromosome transitions from being one chromatid to two sister chromatids during the S phase of the cell cycle, specifically during DNA replication. This is when the DNA is duplicated, and each replicated DNA strand forms a sister chromatid with the original strand, creating a pair of identical chromatids joined at the centromere.

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.
During which phase of the cell cycle do chromatids form?
When a single chromosome is replicated, two sister chromatids are produced. After cell division, each of the chromatids is a chromosome for the daughter cell.
There are 4 chromatids in a?
A chromatid is one half of a duplicated chromosome, so typically there are 2 chromatids in a chromosome.
How does a single pair of sister chromatids differ from a single unduplicated chromozone?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
How does a pair of sister chromosome differ from a single unduplicated chromosome?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
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 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."

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.
During which phase of the cell cycle do chromatids form?
When a single chromosome is replicated, two sister chromatids are produced. After cell division, each of the chromatids is a chromosome for the daughter cell.

How does a single pair of sister chromatids differ from a single unduplicated chromozone?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
How many DNA molecule in a chromatid?
A chromatid contains one DNA molecule, which is a duplicated chromosome consisting of two identical sister chromatids.
How does a pair of sister chromosome differ from a single unduplicated chromosome?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
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.

What is the difference between a chromatid and a sister chromatid?
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
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 each chromosome have only one chromatid?
Each chromosome has only one chromatid during most of the cell cycle, as chromatids are formed during DNA replication. Each chromatid is an identical copy of the original chromosome. When chromatids condense and pair up during cell division, they form a chromosome with two sister chromatids.
