The threadlike structures inside the nucleus of the cells are called the chromosomes.
Chromosomes are the carrier of heredity genes.
DNA
The center of the cell is called the nucleus. It houses the cell's genetic material and controls the cell's activities.
In animal cells, the nucleus is a round or oval structure enclosed by a double membrane called the nuclear envelope. It contains genetic material in the form of chromosomes, which are visible as thread-like structures during cell division. The nucleus also contains a dense region called the nucleolus, involved in ribosome production.
Genetic material, composed of DNA that is packaged into string-like structures called chromatin, makes up a region called the nucleolus, which is inside the nucleus of a cell.In eukaryotes, the genetic material is found within the nucleus of the cell in a form of chromatins. In prokaryotes, the genetic material is suspended in a region known as nucleoid and also contains circular DNA called plasmids.

Chromatin- granular material visible within the nucleus
Granular disintegration is the process by which rock or other materials break down into smaller particles due to physical weathering factors such as freeze-thaw cycles, temperature changes, or abrasion. This can result in the fragmentation of the material into granules or grains.
Incipient nucleus
In the inter-phase nucleus of the cell is located a threadlike genetic material called chromatin.
The nucleolus and genetic material form the nucleus.
DNA
The jelly-like material within the nucleus is called the nucleoplasm.
Bacteria belong to a group called prokaryotes which have no membrane bound genetic material (a nucleus).
Monerans that do not have an organized nucleus are called prokaryotes. They are characterized by having genetic material that is not enclosed in a membrane-bound nucleus.
It is called cytoplasm.
