Assuming random distribution of nucleotides, the average number of fragments generated upon digestion of a circular DNA of size 4.3 × 105 bp with AluI(5′-AG↓CT-3′) is ______ × 103.
-
- 1.48 to 1.58
- 1.68 to 1.7
- 5.68 to 6.721
- All of the above
Correct Option: B
| Average number of fragments generated = |  | × | × | × |  | × 4.3 × 105 | ||||
| 4 | 4 | 4 | 4 |
| = | = 1.68 × 103 | |
| 256 |
