When can variation at SNPs be detected using standard gel electrophoresis?

Question

Quizplus · Accepted Answer

Variation at SNPs can be detected using gel electrophoresis when the SNP is at a restriction site and the corresponding restriction enzyme is used in the experiment. This is because the restriction enzyme will cut the DNA at the SNP site, resulting in fragments of different lengths that can be distinguished by gel electrophoresis. The other options listed do not involve gel electrophoresis or do not specifically address how SNPs can be detected using gel electrophoresis.
