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. template maker sarkari resultWebDNA stands for deoxyribonucleic acid (DNA) and it’s a molecule found in the nucleus of plant and animals cells.
