WebDNA sequencing is the process of determining the sequence of nucleotides (As, Ts, Cs, and Gs) in a piece of DNA. In Sanger sequencing, the target DNA is copied many times, making fragments of different lengths. Fluorescent “chain terminator” nucleotides mark the ends of the fragments and allow the sequence to be determined. WebDNA is packaged into structures called chromosomes. Some tests look for changes in chromosomes rather than gene changes. Examples of these tests are karyotype and chromosomal microarrays. Gene expression. …
