Do prokaryotes have a chromosome?
Answer

Hint: Chromosomes are structures found in cells that allow traits to be handed down through generations during reproduction. True chromosomes can only be found in eukaryotic cells with a properly arranged nuclear nucleus.
In eukaryotes, the genetic material is contained within a membrane, but in prokaryotes, this membrane-bound organelle is lacking. As a result, the chromosome remains in contact with the cell's cytoplasm. The presence of histone proteins is absent in prokaryotes.
Complete answer:
The eukaryotic chromosome is found inside the nucleus, whereas the prokaryotic chromosome is found in the nucleoid or lacks a membrane-bound organelle to encapsulate the genetic material. Eukaryotic chromosomes are made up of DNA that is firmly wrapped around proteins.
A well-organized nucleus is not present in prokaryotic cells. There are no genuine chromosomes in prokaryotes because histone proteins are lacking. Because prokaryotes, such as bacteria, do not have chromosomes, they have circular DNA instead. True chromosomes can be found in eukaryotic cells, such as those found in plants and animals.
Prokaryotic cells lack a well-defined nucleus. They have a nucleoid in their cytoplasm, which is where the genetic material is stored.
The nucleolus is a structure found in eukaryotic cells' nuclei. Proteins and RNA make up the site.
The size and cell organelles of prokaryotic cells differ from those of eukaryotic cells. Prokaryotic cells are smaller than eukaryotic cells in size. Only eukaryotes have important cell organelles such as mitochondria, endoplasmic reticulum, chloroplasts, and Golgi bodies.

Note:
| EUKARYOTIC CHROMOSOMES | PROKARYOTIC CHROMOSOME |
| A linear chromosome is present in them. | A circular chromosome can be found in them. |
| They are present in the nucleus, a membrane-bound organelle. | They are found in a nucleus structure termed a nucleoid and are not encased in a membrane-bound organelle. |
| The DNA is wound around the histone proteins, and there is additional coiling and folding that occurs in the chromosome. | Due to the presence of nucleoid-associated proteins, the DNA is present in supercoiled form. |
| One or more chromosomes can be present in a single cell. | A single chromosome can be found in a single cell. |
| Multiple replication origins can be found in them. | There is a single replication origin present in them. |
