What occurs in prokaryotes?
Prokaryotes, especially bacteria, have no nuclear membrane around their cellular DNA. Besides, they are considered to be unicellular. Therefore, cell division in prokaryotes is different from that of eukaryotes. Even though prokaryotes' cells do not go through the mitosis process, their result is the same. In this case, the single chromosome replicates, after which the two copies that result, split further into two separate halves. Among prokaryotes, cell division occurs through binary fission.
