Depending on where the died fragments start, the smallest parts end up way on the other side. The gel acts as a filter and the electrical current acts as... the current to push the fragments through the gel. Being that they're small... those fragments have an easier time getting through the gel. The bigger fragments are closer to where the fragments started cause they're big and have a harder time going through the gel. Eventually you should have like areas in the gel that look cool and CSI like, as if you were testing for DNA samples. Sadly that may not always happen, being as... well this is reality and not show biz. Good luck though on your next/first attempt.

What is a technique for sorting DNA fragments by length?
Agarose gel electrophoresis is a common technique used to separate DNA fragments based on their size. In this method, DNA fragments are loaded into wells at one end of a gel and then subjected to an electric field, causing the fragments to migrate through the gel based on their size. The smaller fragments move faster and travel farther than larger fragments, allowing for sorting by length.
Are the DNA fragments in band 4 larger or smaller than those of band 1?
The size of DNA fragments in band 4 should be smaller than those of band 1. The fragments can be separated by electrophoresis, with the smaller fragments migrating farther than the larger ones.
What procedure is used to separate and analyze DNA fragments by placing a mixture of DNA fragments at one end of a porous gel and supplying an electrical voltage to the gel?
agarose gel electrophoresis
How does the DNA end up sorting itself in the gel?
If by the gel you mean in an electrophoresis test, then the DNA sorts itself out relative to the size of the DNA molecules. The shortest being closest to the positive end, and the longest near the negative end.
Why do the DNA fragments move to the positive end of the tray?
DNA fragments move toward the positive end of the gel tray during electrophoresis because DNA is negatively charged due to its phosphate backbone. When an electric current is applied, the negatively charged DNA molecules are attracted to the positive electrode. This movement allows the fragments to be separated based on size, with smaller fragments traveling faster and farther than larger ones.

Where do the shorter DNA bands end up reaching at the completion of gel electrophoresis?
the smallest DNA fragments are observed by a process called elcrophoresis where the DNA fragmnets placed on this gel will migrate according to their lenght so the smallest fragment will migrate the fastest and they will be found at the bottom .

How does gel electrophoresis separate DNA by size?
Gel electrophoresis separates DNA fragments based on their size through an electric current. The negatively charged DNA molecules move towards the positively charged end of the gel. Smaller fragments move faster and migrate further through the gel than larger ones, resulting in the separation of DNA fragments by size.

Would you agree that if a person believes that their smallest DNA fragment is the band nearest the negative pole if the gel?
It is not possible for DNA fragment to be found towards the negative pole of gel. Reason being that the DNA itself is a negatively charged molecule and will always move towards the positive pole when the gel is run. Regarding the smallest fragment, it is impossible to find a band near the negative pole. When the gel is running the smallest fragment runs ahead of all the fragments. It could be found near the positive end, and also possible that if it is too small and the gel is not turned off on correct time then the fragment may overrun the gel from positive end.
How does DNA and gel electrophoresis relate?
Gel electrophoresis separates an individual's DNA fragments from one another according to size. An electric current repels a mixture of the negatively-charged DNA fragments through microscopic pores in the gel from the negative to the positive electrode. Upon completion, the separated fragments of DNA can be visualized as a ladder of small bands in the gel by staining with a methylene blue dye solution or smaller DNA segments move more easily through the gel.
In gel electrophoresism DNA fragments migrate toward one end of a gel because that are?
In gel electrophoresis, DNA fragments migrate toward one end of a gel because they are negatively charged and are attracted to the positive electrode at the opposite end of the gel. The smaller DNA fragments move faster through the gel matrix while the larger fragments move more slowly.
What does the charge of DNA have to do with DNA fingerprinting?
DNA is of a negative charge. So when gel electrophoresis is used on it the DNA fragments are attracted to the positive end of the electrophoresis. The fragments of different lengths travel down the gel towards this end. The longer length fragments travel less and so are farther from the positive end. By looking at these DNA fragments, which are created by cutting DNA with restriction enzymes one can compare and contrast DNA. Thus DNA fingerprinting can take place based on the different restriction sites in DNA (cut by the enzymes) forming different length segments of DNA.
What is true of the DNA fragment band closest to the positive end of the gel?
they are the smallest.
