smallest and lightest
largest and heaviest

Answer 1

In electrophoresis, smaller and lighter fragments move the furthest through the gel. The gel creates a matrix that impedes larger molecules more than smaller ones, allowing the smaller fragments to migrate faster and further when an electric current is applied. Therefore, the correct answer is:

smallest and lightest.
