Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is evidence that a cell is prokaryotic?
A
Cell wall
B
Cytoplasm
C
Ribosome
D
Nucleoid Region
Explanation: 

Detailed explanation-1: -The nucleoid region is a membrane-less region in the prokaryotic cell where most, if not all, of the DNA in the cell is located. The nucleoid is located directly in the cytoplasm, allowing the DNA to be n contact with the cell membrane. The DNA in prokaryotes is circular and is referred to as a plasmid.

Detailed explanation-2: -All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles.

Detailed explanation-3: -The nucleoid is essential for controlling the activity of the cell and reproduction. It is where transcription and replication of DNA take place.

Detailed explanation-4: -Most prokaryotes carry a small amount of genetic material in the form of a single molecule, or chromosome, of circular DNA. The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane.
