|
Prokaryotic has circular DNA and eukaryotic has double helix DNA.
|
|
|
Prokaryotic has DNA in the nucleus and eukaryotic has DNA in the cytoplasm.
|
|
|
Prokaryotic cells do not have DNA, but eukaryotic cells do.
|
|
|
Prokaryotic cells have double helix DNA and eukaryotic cells have circular DNA.

Detailed explanation-1: -Prokaryotes contain circular DNA in addition to smaller, transferable DNA plasmids. Eukaryotic cells contain mitochondrial DNA in addition to nuclear DNA. Eukaryotes separate replicated chromosomes by mitosis, using cytoskeletal proteins, whereas prokaryotes divide more simply via binary fission.
Detailed explanation-2: -Prokaryotes contain a single, double-stranded circular chromosome. Eukaryotes contain double-stranded linear DNA molecules packaged into chromosomes. The DNA helix is wrapped around proteins to form nucleosomes.
Detailed explanation-3: -Prokaryotes have circular DNA while eukaryotes have linear chromosomes.
Detailed explanation-4: -Prokaryotic DNA is double-stranded and circular in structure. It is seen in a less organized structure present at the center of the bacterial cell called nucleoid. Unlike nucleus present in eukaryotes, these are non-membrane-bound structures that contain the circular, double-stranded DNA of prokaryotes.
Detailed explanation-5: -While most prokaryotes, like E. coli, contain a single circular DNA molecule that makes up their entire genome, recent studies have indicated that some prokaryotes contain as many as four linear or circular chromosomes. For example, Vibrio cholerae, the bacteria that causes cholera, contains two circular chromosomes.
