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.

One half of a duplicated chromosome?
A duplicated chromosome consists of two chromatids.
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.
What is sister chromatin?
A sister chromatin is one half of a chromosome. Two sister chromatids come together connected by a centromere to create one chromosome.
What is the next step after chromosome duplication?
is it two chromatids or spindles
Each chromosome consists of 2 what?
Chromatids
One half of a duplicated chromosome?
A duplicated chromosome consists of two chromatids.
How many chromatids does each chromosome have before S-phase?
There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
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.
Two of these make a chromosome?
Two chromatids connected at the centromere make up one chromosome.
How many chromatids are present in a chromosome t the beginning of mitosis?
Two chromatids are present in a chromosome at the beginning of mitosis.
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
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.

Are chromosomes and chromatid the same thing?
Two chromatids held by the centromere is called a chromosome.
How many chromatids are in a tetrad?
All tetrads contain four chromatids. Each "leg" is one chromatid.2Tetrad = 2 homologous chromosomes1 homologous chromosome has 2 chromatids joined together by a centromere.That means that there are four chromatids in a tetrad
What is sister chromatin?
A sister chromatin is one half of a chromosome. Two sister chromatids come together connected by a centromere to create one chromosome.
How many chromatids makes up a chromosome when a cell is ready to divide?
the correct answer is 25
After replication each chromosome harbors what?
two sister chromatids
