Detailed explanation-1: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Detailed explanation-2: -Bacteria are prokaryotes, lacking well-defined nuclei and membrane-bound organelles, and with chromosomes composed of a single closed DNA circle.

Detailed explanation-3: -Does Bacteria Have a Nucleus? Bacteria cells are prokaryotic cells; therefore, they lack a nucleus. In eukaryotic cells, the nucleus is where the DNA is housed. However, in bacteria cells, the DNA or genetic information is found floating freely in the cytoplasm of the cell.

Detailed explanation-4: -Bacteria, of course, have no nucleus and therefore also nuclear membrane. genetic information-DNA is organized into numerous chromosomes and is packaged in the nucleus. The nucleus is bounded by a membrane mRNA, tRNA and rRNA are made in the nucleus and shipped out into the cytoplasm.

Detailed explanation-5: -Prokaryotic cells, such as bacteria, have a free-floating chromosome that is usually circular and is not enclosed in a nuclear membrane. Instead, the DNA simply exists in a region of the cell called the nucleoid.
