WebbDNA 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. Webb12 okt. 2024 · Jeffreys' DNA profiling - the process of determining an individual's DNA characteristic - is now used worldwide in forensic science to assist police and in paternity disputes.
