Question

Quizplus · Accepted Answer

The migration rate of linear DNA molecules in agarose or polyacrylamide gels is inversely proportional to their size, i.e., smaller molecules migrate faster than larger ones. This is because smaller molecules can move more easily through the gel matrix, experiencing less resistance from the gel structure. The migration rate is not dependent on the DNA sequence, such as AT or GC content, but only on the size of the DNA fragments.
