I: | The lack of 35S-labeled DNA remaining in the solution after the bacteriophages had been allowed to adsorb to the bacteria showed that the phage DNA was transferred into the bacterial cell. |
II: | The presence of almost all the radioactive 32P in the solution showed that the protein coat that protects the DNA before adsorption stayed outside the cell. |

3. | Both I and II | 4. | Neither I nor II |
I: | Radioactive sulfur-35 was used to label the DNA contained in the T2 phage |
II: | Radioactive phosphorus-32 was used to label the protein sections of the T2 phage |

Assertion (A): | VNTRs are the basis of DNA fingerprinting by RFLP |
Reason (R): | VNTRs are polymorphic and are inherited |
