    Sanger Sequencing by Hand: Using Paper Clips to Demonstrate Chain Termination
    Sanger sequencing is commonly taught with a hands-on approach. Sanger sequencing involves chain termination by dideoxynucleotides, because they are missing the oxygen on the 3’ carbon atom, which is required for the addition of subsequent...
