Assume that you have cut λ dna with the restriction enzyme hindiii. you separate the fragments on an agarose gel and stain the dna with ethidium bromide. you notice that the intensity of the stain is less in the bands that have migrated closer to the "+" pole. give an explanation for this finding.

The smaller fragments bind less stain than larger fragments that are near the origin. This is because the smaller fragments migrate toward the "+" pole. The ethidium bromide is a stain that makes the bands to fluoresce when they are excited with the ultraviolet light.

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
