Chromatin is intertwinted mass of fine thread-like structure made of DNA and protein. During cell division (mitosis and meiosis), chromatin condenses to form thicker rod-like structures called chromosomes. Each chromosome consists of two similar halves called chromatids. Formation of chromosomes having two similar halves or chromatids is meant for equitable distribution of chromatin which is hereditary material.

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.
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.
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical 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 next step after chromosome duplication?
is it two chromatids or spindles
Point on a chromosome where chromatids are attached?
Centromere
Why does a chromosome has two sister chromatids?
because it can
What are the sister chromatids in a chromosome attached by?
centromere
Each chromosome consists of 2 what?
Chromatids
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 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.
The replicas of chromosomes that form during prophase are called what?
During prophase, a chromosome is composed of tightly coiled DNA and protein molecules. Each chromosome exists as a pair of identical sister chromatids which are held together at the centromere.
