M-Digested DNA bands
N-Undigested DNA bands
M: Largest DNA bands (closest to the wells)
N: Smallest DNA bands (furthest from the wells)
Agarose gel electrophoresis is a widely used laboratory technique for separating and analyzing DNA, RNA, or proteins based on their size and charge. It utilizes an agarose gel matrix, an electrical field, and a buffer solution to separate molecules according to their molecular weight.
In agarose gel electrophoresis, DNA fragments are separated based on their size. Smaller fragments move faster through the gel matrix and migrate further from the wells (where the DNA is loaded) than larger fragments.
Thus, the correct option is C: M-Largest DNA bands & N-Smallest DNA bands
Agarose gel electrophoresis is an essential tool in molecular biology, enabling the analysis of genetic material and helping researchers visualize and quantify DNA, RNA, or proteins in various experiments.
M: Largest DNA bands (closest to the wells)
N: Smallest DNA bands (furthest from the wells)
Hence, the correct option is C: M-Largest DNA bands & N-Smallest DNA bands
