फरक स्पष्ट करा
उत्तर
| Repetitive DNA | Satellite DNA |
| It is the section of DNA that contains the same base sequences repeated numerous times. The repeating sequences in this repetitive DNA might be tandem or interspersed repeatedly. | The portion of repetitive DNA contains repeated sequences in tandem, also known as tandemly repetitive DNA. |
| Repeating units can be a few base pairs long or hundreds to thousands of base pairs long. | It has small sequence repetitions (up to 60 bp long). |
| They appear as bright bands in the CsCl density gradient study. | In CsCl density gradient analysis, it is seen as small dark bands. |
| During density gradient centrifugation, repetitive DNAs are isolated from bulk genome DNA by distinct peaks. | It is separated from repetitive DNA as a satellite. Satellite DNA has been divided into small peaks. |
