Final answer:
In a bacterium, DNA is found in the nucleoid, a region that is not enclosed by a membrane. This is in contrast to eukaryotic cells which have a membrane-bound nucleus.
In a bacterium, we will find DNA in _the nucleoid_
So the correct answer is Option C
Step-by-step explanation:
In a bacterium, we will find DNA in the nucleoid. The nucleoid is where the genetic material of a prokaryotic cell is located. Unlike eukaryotic cells, which have a membrane-bound nucleus, prokaryotic cells, such as bacteria, have their DNA concentrated in a region called the nucleoid.
This region is not surrounded by a membrane. Other cellular structures found in both prokaryotic and eukaryotic cells include ribosomes, which are sites of protein synthesis, and the plasma membrane, which surrounds the cell. However, structures like mitochondria are absent in prokaryotic cells like bacteria. In eukaryotic cells, DNA is found within the membrane-bound nucleus, and specific organelles such as mitochondria and chloroplasts have their own DNA, which supports the endosymbiotic theory.
the correct answer is Option C
