Which of these dna molecules is the shortest? what?

The original context in this question is: In this example the marker DNA includes fragments that have 23,130, 9,416, 6,557, 4,361, 2,322, 2,027, and 564 base pairs.

DNA molecules, if measured by length, is directly proportional to the number of base pairs. In this question, the DNA molecule with only 564 base pairs is the shortest. On the other hand, the DNA molecule with 23130 base pairs is the longest.
