WebDNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and ... WebA series of bands appear on the gel because the DNA negative charge is getting pulled to the positive charge of the electrophoresis tray, which makes the DNA cross the gel leaving behind tracks. 3: Identify Cause: Why is the largest DNA fragment band found closest to the well in which it was placed?
