because DNA is of negative charge thus it will travel towards the positive pole due to attraction.....and the movement of the DNA is also facilitated by the repulsion of the positive pole which is near by to DNA
DNA is negatively charged, and since opposites attract, it moves toward the positive end.
DNA is negative, so it migrates toward the positive end (of the electrophoresis gel, I'm assuming)
Because the DNA backbone is packed with negative molecules, and the cathode will attract negatively charged particles.
Phosphate groups of DNA are negatively charged,so DNA move towards possitive charge.
The natural charge of DNA molecule (deoxyribonucleic acid) is negative and goes towards the positive pole or anode.

DNA migrates from the black (negative) terminal to the red (positve) if you place your DNA in the wells adjacent to the red terminal in would in a short time migrate off the end of your gel into the running buffer. Most people who run DNA gels have done this at least once.
it's called electrophoresis. The DNA will be separated based on size and charge. Because DNA is negative, it will move toward the positive side of the voltage box and usually smaller molecules move faster than larger ones.
An electric current. DNA is negatively charged so it migrates toward the positive pole of the gel set up.
DNA molecules have a negative charge due to the phosphate groups in their backbone. In electrophoresis, an electric field is applied across a gel matrix, causing DNA fragments to migrate towards the positive electrode. The negatively charged DNA molecules are attracted to the positive electrode and move through the gel at different rates based on their size, with smaller fragments moving faster than larger ones.
Assuming you're talking about an electrophoresis gel for separating DNA: DNA is itself negatively charged because it contains phosphate groups. Thus, when you apply a current, it will move towards the positive electrode at the other end of the gel. If the DNA were placed at the positive end of the gel, it would migrate backwards and you'd lose the sample.
DNA molecules are negatively charged. When places in an electric field, like in an gel during the process of electrophoresis, they all move toward the positive electrode.
DNA is negatively charged and a current is running through the gel with the positive pole and the foot of the gel run, so the DNA migrates from the head of the run towards its oppositely charged pole.
The negatively charged phosphate groups of the DNA causes them to move only towards the positive poles

When DNA samples are run (i.e. in gel electrophoresis) they start at the negative end. This is because DNA carries a negative charge, and so will move towards the positive electrode. Therefore the DNA is placed at the other end (so it has room to move).
Length. DNA has a natural negative charge - and so will move towards the positive electrode. Larger fragments move more slowly than shorter ones - so the sizes of fragments can be determined.
1. DNA is negatively charged by placing the sample wells closest to the negative electrode we can give the DNA more room to spread out in accordance to its size and charge. The amount the DNA moves from the well is directly linked to its charge and size. Since DNA is only negatively charged leaving space for the DNA to move in the positive direction would be a waste of space because it is not possible.
it's called electrophoresis. The DNA will be separated based on size and charge. Because DNA is negative, it will move toward the positive side of the voltage box and usually smaller molecules move faster than larger ones.
DNA is naturally negative therefore when a positive charge in put to one side of the gel the DNA wants to move towards it.
An electric current. DNA is negatively charged so it migrates toward the positive pole of the gel set up.
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.
