Prokaryotic cells

The vast majority of prokaryotic cells have a single copy of each gene, which is why they are called haploid. The genomes of these cells are compact and have little repetitive DNA.

Unlike eukaryotes where the DNA is located within the nucleus, the DNA of prokaryotes is found in a circular chromosome in the nucleoid within the cytoplasm; which is why transcription and translation occur simultaneously.

The cell cycle of prokaryotic cells consists of a long period of growth, where the cell replicates its DNA, followed by a form of cell division called binary fission.

In binary fission, bacteria perform cell division. It is similar to mitosis, but its purpose is different. It is an asexual reproduction where a prokaryotic organism duplicates its genetic material , DNA, and then divides into two parts (cytokinesis), where each of these has a copy of DNA.
