In the Sanger method for DNA sequencing,the gels are read from bottom to top,since the smallest fragments travel farthest in the sequencing gel.

Question

Quizplus · Accepted Answer

The Sanger method for DNA sequencing involves fragmenting DNA and separating the fragments by size using a sequencing gel. The smallest fragments will travel farthest in the gel, meaning they will be at the bottom of the gel. Therefore, the gels are read from bottom to top to determine the sequence of the DNA fragments.
