Consider the following statements:
| I: | The VNTRs belong to a class of satellite DNA called as mini-satellite. |
| II: | Southern blotting is the transfer of DNA fragments to a filter cellulose membrane. |
| III: | VNTRs are used in DNA fingerprinting as they do not show any variations and are not inherited. |
Which of the above statements are true?
| 1. | I and II only | 2. | I and III only |
| 3. | II and III only | 4. | I, II, and III |
