Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The word prokaryotic means?
A
having only one cell
B
having more than one cell
C
DNA is not in a nucleus
D
DNA is in a nucleus
Explanation: 

Detailed explanation-1: -A prokaryotic cell does not have a defined nucleus; the nuclear material in a prokaryote is known as a nucleoid . DNA present in the nucleoids of prokaryotes is of circular, double stranded type which is tightly coiled.

Detailed explanation-2: -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-3: -prokaryote, also spelled procaryote, any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes.

Detailed explanation-4: -Answer and Explanation: Prokaryotic cells do not contain a true nucleus. They consist of genetic material which is located in a nucleoid region. They lack a nucleus with a nuclear membrane.

Detailed explanation-5: -The nucleus is a membrane-bound organelle inside eukaryotic cells that contains DNA. It is not found in prokaryotes and this is in fact a major difference between prokaryotes and eukaryotes.
