Assuming you are using a gel, the fragments are distributed so that the smaller pieces move further away from the starting point, and the larger pieces are closer to the start. They also move according to the electrical charge they have, so negaitvie charged pieces will move further along the gel.
Gel electrophoresis
Electrophoresis
Electrophoresis. Restriction enzymes are used to cut DNA into fragments. Solutions containing these fragments are placed on the surface of a gel to which an electric current is applied. The electric current causes the DNA fragments to move through the gel. Because smaller fragments move more quickly than larger ones, this process separates the fragments according to size.
Smaller DNA fragments move faster and further in gel electrophoresis compared to larger fragments. The distance migrated by DNA fragments in gel electrophoresis is inversely proportional to their size.
The largest DNA fragments travel more slowly through the agarose gel due to their size, so they don't move as far from the well as smaller fragments during gel electrophoresis. This results in the largest fragments being closest to the well after electrophoresis is completed.

In gel electrophoresis, a DNA ladder serves as a reference for determining the sizes of DNA fragments being analyzed. It contains DNA fragments of known sizes, which help in estimating the sizes of unknown DNA fragments by comparison. This aids in accurately identifying and analyzing the DNA fragments present in the sample.
gel electrophoresis, a technique that uses an electric field to separate DNA fragments based on size. The smaller DNA fragments move faster through the gel, while larger fragments move more slowly. This allows researchers to determine the sizes of DNA fragments in a sample.

The pattern of dark bands on photographic film in gel electrophoresis of DNA fragments is called a gel electrophoresis pattern. The dark bands are formed by DNA fragments of different sizes that have been tagged with a fluorescent or radioactive marker. The position of the bands indicates the size and quantity of the DNA fragments.
Gel Electrophoresis
The bands in gel electrophoresis represent different sizes of DNA fragments.
Gel electrophoresis separates and analyzes DNA fragments by passing an electric current through a gel matrix, causing the DNA fragments to move based on their size and charge.
