What is the purpose of the electrical current in gel electrophoresis?
The electrodes are able to pull the fragments towards the ends of the gel. If you're using DNA, which has a negative charge, it will be attracted to the positive electrode.
How does DNA charge affect movement in electrophoresis?
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.
Why does DNA move toward the positive electrode?
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
What does a negative charge in entropy indicate?
When an objects gets negative charge it attracts positive charged objects, repel negative charged objects and even attracts neutral copper rod. Neutral copper rod is attracted towards both both negative and positive charged objects due to the availability of mobile electrons in the copper rod.
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.
Do positively charged DNA molecules flow to the negatively charged poles in the electrophoresis chamber?
Yes. Positive(+) goes to negative(-). During gel electrophoresis, the positively charged molecules move to the negative cathode, and vis versa the negatively charged molecules move towards the positive anode.
What is the purpose of the electrical current in gel electrophoresis?
The electrodes are able to pull the fragments towards the ends of the gel. If you're using DNA, which has a negative charge, it will be attracted to the positive electrode.
Does DNA samples start at the negative or the black charge?
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).
What color associated with charge does DNA move towards in a gel electrophoresis box?
it is positive
A what is electrically neutral?
It does not need a positive or negative charge to balance out its atom lingo, so has no charge that pulls it towards other atomic particles. Therefore, it is commandeering a neutral state of charge, or no charge at all.
Why is a neutral object attractred to a charged object?
This is known as electrostatic induction. As charged object (say positive) is brought near by the neutral object the opposite charges i.e. negative would get attracted towards and positive charges would be pushed away. Yet the object is neutral though the charges got separated. Now due to attraction of unlike charges the neutral is attracted towards the charged one.
An electrically neutral object can be attracted by a positively charged object because?
A neutral pith ball is still "charged", it just doesn't display excessively charged behavior. Since it is neutral, having nearly equal positive and negative charge, the proximity of the positively charged pith ball still attracts the negative charge present in the ball, inducing polarization moving the ball closer to the positively charged one. Once they make contact, the conductibility of the pith ball quickly accepts excess charge from the other, creating a like charge repulsion.
What is gel electrophoresis and how is it used to analyze?
Gel electrophoresis is a common method to study DNA. It is a very basic way of comparing the mass (mostly size or length of DNA). The main principle behind gel electrophoresis is that DNA has a slight negative charge. When put in a gel (usually agarose gel) DNA will travel through the gel towards a positive charge, which is generated by the electrophoresis machine. The basic idea behind it, is that DNA will travel through the gel towards the positive pole and away the negative pole of the electrophoresis machine. The smaller the fragment, the further it will travel towards the positive pole, as it will go through the gel quickly. The larger fragments will travel slower towards the positive pole, and will travel less compared to the small fragments. This is how one can quickly compare size of DNA fragments, and possibly even compare between 2 or more DNA strands and find similarities.
What effect does a negative object have on a neutral object?
If the event horizon (space, in this case) of one of the items is breeched by the other and touch, the neutral object becomes negatively charged. If they never touch, they both remain in their present condition. The neutral object's condition will never affect the charge of the negatively charged object, whether they touch or do not touch. The negatively charged item's condition will never change, regardless of physical touch between the two items. ***************Contributed by Czar Acumen*******************

Gel electrophoresis separates DNA fragments on the basis of differences in their?
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.
