Answer :
The shortest DNA molecule is Fragment A. that is due to the fact it's far positioned on the top close to the loading well.
Fragment B is simply below Fragment A, and Fragment C is about midway down the gel. Fragment D is just underneath Fragment C, and Fragment E is the furthest down the gel, closest to the positive electrode.
The manner gels paintings is that DNA molecules are loaded into the properly at the top of the gel and then an electrical cutting-edge is applied. The smaller molecules pass quicker and end up further down the gel. As Fragment A is the closest to the loading properly, it's miles the smallest molecule, and therefore the shortest. therefore, Fragment A is the shortest DNA molecule.
