Therefore, whenever a ddNTP is added to a growing DNA strand, it is unable to chemically bind with the next nucleotide in the chain, and the DNA strand stops growing. Figure 3: By adding together information about all of the truncated strands, researchers can determine the nucleotide sequence of the DNA target.
