Solution
| Sr. No. | Repetitive DNA | Satellite DNA |
| 1. | DNA sections where base sequences are repeated many times. | Repetitive DNA sequences that are repeated back-to-back (tandemly). |
| 2. | Repeating units can range from a few to thousands of base pairs. | Consists of highly repetitive, typically shorter sequence units. |
| 3. | They form distinct major peaks in density gradient analysis. | They appear as small peaks (satellite peaks) in density gradient analysis. |
| 4. | These sequences are isolated from the bulk genomic DNA. | They are separated specifically from bulk genomic DNA during centrifugation. |
