Determining the exact sequence of nucleotide bases in a strand of DNA to better understand the behavior of a gene.
Determining the order (or sequence) of the DNA bases (A, G, C, or T) that make up a specific gene.
A gene sequence is the order of the A, T, C and G chemicals along a strand of DNA.In some cases, these letters are repeated more than a million times in a single gene.By itself, knowing the order of the A, T, C and G bases does not tell us very much.Scientists still have to translate those strings of letters into an understanding of how the genome works - what the genes do, how genes are related and how they all work together.

Determination of the sequence of nucleotide bases in a strand of DNA.
Technology used to interpret the sequence of the nucleotides (adenine, cytosine, guanine, and thymine) in a DNA sample from bands on an X-ray film image. Scientists use a combination of lasers, high-precision optics, and computer software to determine the sequence of fluorescently tagged DNA molecules.
The determination of the sequence of bases in a DNA strand. The two most widely used methods are the chain-termination method, developed by Sanger and the chemical method developed by Maxim & Gilbert.
A laboratory technique for identifying nucleotide sequences in a DNA fragment. Sequence comparisons may help researchers find mutations responsible for a disease.
