Solution:
The given diagram represents the gel electrophoresis technique. It is used to separate DNA fragments based on their sizes. The DNA fragments that have larger sizes travel a shorter distance than the smaller size DNA fragments from the wells under the influence of an electric field. Hence, 'M' represents the largest DNA bands since it has travelled a less distance from the well when compared to the distance travelled by the fragment 'N'.
