WebFeb 21, 2024 · The genetic material of prokaryotic cells in a single chromosome is made up of a single strand of DNA. A critical protein, histone protein, that is found bound in the chromosomes of eukaryotes is absent in prokaryotic cells. Prokaryotic cells also lack the nucleolus and the mitotic apparatus. WebJul 31, 2024 · The genes are located on the chromosomes at a specific location called the locus. The genes and the DNA are compactly packed in the chromosome.
