chromosomes
DNA
The nucleus holds the cells genetic material in eukaryotes. The genome of eukaryotes is sequestered to a membrane bound organelle called the nucleus. The nucleus is the site of replication and transcription.
Deoxyribonucleic acid or DNA.
are densely staining, roughly spherical bodies composed of RNA and protein
The genetic material of a cell is actually the DNA (DeoxyriboNucleic Acid) molecule. In some types of cells this genetic material is packaged alongwith many other chemicals in the form of long thread-like structures called chromosomes and enclosed in a membrane-lined struture. This spherical structure is called nucleus and such cells are called eukaryotes. In other types of cells the genetic material is not enclosed in a nucleus but rather lies exposed to the cytoplasm of the cell. These are the prokaryotic cells of which bacteria are the prime examples. The cells of most higher forms of life (plants and animals) are eukaryotes.

Prokaryotic organisms don't have a nucleus. And also bacteria do not have a nucleus they only have vacuoles as they are thread like material. All of the prokaryotic and archea cells don't have a nucleus. Only eukaryotic cells have a nucleus.
A chromosome is a thread like structure of nucleic acids and protein found in the nucleus of living cells. It carries genetic information in the form of genes.
thread
You fasten material with needle and thread by sewing the material. In most cases, you will place one piece of material on top of another and then stitch the material together with the needle and thread.
A thread-like molecule in the nucleus composed of DNA is called a chromosome. Chromosomes carry the genetic information in the form of genes and are crucial for cell division and inheritance. Each species has a specific number of chromosomes, and in humans, there are 23 pairs of chromosomes.
In a cell which is not dividing,this DNA is present as part of chromatin material.
