Answer:
The correct option for this question is (2) A circular DNA.
Explanation:
- One circular DNA molecule, or chromosome, makes up the majority of the genetic material carried by prokaryotes.
- Prokaryotes have a nucleoid in the centre of the cell that houses the DNA but is not protected by a nuclear membrane. The genome of prokaryotes is made up of a single double-stranded DNA molecule that is shaped like a loop or circle.
- A nucleoid is the area of the cell that houses this genetic material. Additionally, some prokaryotes include tiny DNA loops called plasmids that are not necessary for typical growth.
- Recent research has revealed that some prokaryotes may have as many as four linear or circular chromosomes, in contrast to the majority of prokaryotes, such as E. coli, which have a single circular DNA molecule that makes up their whole genome.
- For instance, the cholera-causing bacteria Vibrio cholerae has two circular chromosomes.
Thus, circular DNA makes up the genetic material in prokaryotic cells.
