One wаy tо demоnstrаte thаt a chrоmosome contains a single DNA molecule is to use a technique called pulsed-field gel electrophoresis, which can separate DNA molecules up to 107 bp in length. Ordinary gel electrophoresis cannot separate such long molecules because the steady electric field stretches them out so they travel end-first through the gel matrix at a rate that is independent of their length. If the electric field is changed periodically, however, the DNA molecules are forced to re-orient to the new field before continuing their snakelike movement through the gel. The time for re-orientation depends on length, so that longer molecules move more slowly through the gel. The results of pulsed-field gel electrophoresis of the DNA from the yeast Saccharomyces cerevisiae are shown in the following figure. How many chromosomes does S. cerevisiae have?
