Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where is the DNA found in a prokaryotic cell?
A
floating around in the cytoplasm
B
in the nucleus
C
Either A or B
D
None of the above
Explanation: 

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.

Detailed explanation-2: -Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm.

Detailed explanation-3: -The nucleus is where cells store their DNA, which is the genetic material. The nucleus is surrounded by a membrane. Prokaryotic cells do not have a nucleus. Instead, their DNA floats around inside the cell.

Detailed explanation-4: -The DNA/genetic material will be freely floating in the cell cytoplasm. These are primitive cells which lack most of the cell organelles (e.g. mitochondria, Endoplasmic reticulum etc.) The prokaryotic cells consist of bacteria, blue-green algae, mycoplasma and PPLO (Pleuro Pneumonia Like Organisms).

Detailed explanation-5: -Prokaryotic cells comprise bacteria and archaea. Their genetic material isn’t stored within a membrane-bound nucleus. Instead, it is stored in a nucleoid that floats in the cell’s cytoplasm.
