How would you interpret results of DNA restriction analysis by gel electrophoresis if there was a difference in one band?

Question

Quizplus · Accepted Answer

If there is a difference in one band, it means that there is a variation in the DNA between the samples. This could be due to genetic differences or other factors such as mutations. It is important to investigate this variation further to understand its significance. Gel electrophoresis does not need to be repeated if the results are consistent and reproducible. The wrong buffer being used would most likely affect all the bands, not just one.
