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. WebTheir DNA becomes tightly coiled up and the replicated chromosomes become visible as separate units. The chromosomes shorten and thicken and can now be seen as pairs of … how to repair concrete sidewalk
