Detailed explanation-1: -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 . Prokaryotic cells only have a small range of organelles, generally only a plasma membrane and ribosomes.
Detailed explanation-2: -Bacteria are prokaryotes. A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles. The majority of prokaryotic DNA is found in a central region of the cell called the nucleoid. So, bacteria have DNA in their cytoplasm.
Detailed explanation-3: -Bacteria are classified as prokaryotes because they lack a nucleus and membrane-bound organelles. All bacteria are prokaryotes, and while they may have other cellular structures such as a cell wall, cilia, or flagella, they lack a nucleus, making them prokaryotic.
