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
The granular material visible within the nucleus, which consists of DNA coiled around proteins, is called chromatin. Chromatin serves to package DNA into a more compact, dense shape, allowing it to fit within the nucleus while also playing a crucial role in gene regulation and expression. When DNA is relaxed, it is in a less condensed state, making it accessible for transcription and replication. This dynamic structure allows cells to efficiently manage their genetic information.
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 assembly of ribosomes begins in a small dense structure called the nucleolus. The nucleolus is a non-membrane bound structure composed of proteins and nucleic acids found within the nucleus.
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).
