Answer
Difference between Prokaryotic and Eukaryotic DNA :
| S.No. | Prokaryotic DNA | Eukaryotic DNA |
| 1 | It is found in cytoplasm, mitochondria and chloroplast. | It is found in nucleus. |
| 2 | Much less in amount, less than 0.1 Pg. | Much more (> 1 Pg) in amount than prokaryotic DNA. |
| 3 | It is usually circular, double stranded. | It is usually linear, double stranded. |
| 4 | It is naked, without histone. | It is coated with histone. |
| 5 | It can code for fewer proteins. | It can code for far more proteins. |
| 6 | Non-coding introns are absent. | DNA is mosaic of exons (coding regions) and introns (noncoding region). |
| 7 | G : C contents are more than A : T. | A : T contents are more than G : C. |
| 8 | On beating it is denatured as a tangled mass. | It is denatured into 2 separate strands. |
| 9 | It exists singly. | It exists in pairs. |
| 10 | Repeated sequences absent. | Present. |
| 11 | Very little part of DNA is functionless. | Greater part of DNA is noncistronic and functionless. |
