Di-deoxy sequencing gel with annotation
Di-deoxy sequencing is a way to determine the order of bases (A,C,G and T) in a piece of DNA. A set of 4 lanes (one for each base) is needed to sequence any given piece of DNA. Wherever a black band appears in a particular lane that base is present. By reading off the order of bands across the four lanes the sequence of bases can be worked out. This is illustrated for the section of the sequence marked out by the lines.
