WebThe two fragments which are not visualised on the gel are the smallest two (564 and 125 bp respectively). This is because they do not bind sufficient ethidium bromide to be clearly visualised. Moreover, they would be more prone to diffusion than larger bands which adds to their poor distinction in the gel.
