Quizplus · Accepted Answer

Gel electrophoresis is commonly used to separate DNA fragments based on their size. In the case of chain-terminated DNA fragments, they are separated by running them through a gel matrix that separates the fragments based on their size. This technique is commonly used in Sanger sequencing, which is a method for determining the nucleotide sequence of DNA.
