DNA sequencingdetermination of the order of NUCLEOTIDES in a DNA molecule or part thereof. A number of techniques is available to determine a DNA sequence, for example the chain-terminator DNA sequencing procedure (see DIDEOXYRIBONUCLEOTIDE). Generally such techniques rely on the power of polyacrylamide gels to resolve NUCLEIC ACID molecules that differ in length by only a single nucleotide. Ladders of DNA fragments are formed on the gels following ELECTROPHORESIS. Both manual and automated methods of sequencing are available.
