In gel electrophoresis, DNA fragments are separated based on:
A)their sequence.
B)their size.
C)their charge.
D)how many adenine bases are in the fragment.
E)how many thymine bases are in the fragment.

Question

Quizplus · Accepted Answer

Gel electrophoresis separates DNA fragments based on their size. The DNA samples are loaded into wells at one end of a gel and an electric current is applied, which causes the DNA fragments to move through the gel towards the positive electrode. Smaller fragments move more quickly through the gel than larger fragments, resulting in separation of DNA fragments based on their size.
