What is the relationship between the size of the DNA fragment and the distance that it migrates from the well?
. Because DNA is a negatively charged molecule, it will migrate through the gel toward the positive electrode (recall that opposite charges attract). The rate of migration of DNA through the agarose depends on the size of the DNA fragment. The smaller the fragment, the faster it can move through the gel. Another important factor is the concentration of agarose in the gel. The higher the concentration of agarose, the more it slows down the movement of all the DNA fragments.
During gel electrophoresis do long or short fragments travel more quickly toward the positive pole?
Short fragments travel more quickly toward the positive pole during gel electrophoresis. This is because smaller DNA fragments can move more easily through the pores of the gel matrix, leading to faster migration rates compared to larger fragments.
What cause the DNA fragments to move through the gel?
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.
Explain how an agarose gel can separate DNA fragments of different lengths.?
The separation of DNA fragments is based on size. When a DNA sample is run in a gel (electrophoresis), the lighter fragments migrate faster than the heavier (longer) fragments under the influence of an electric current. At the and of the process, the shorter fragments are found at the terminal end of the gel and the longer fragments closer to the origin
Does gel electrophoresis seperate dna fragments?
dna fragments are negatively charged is the answer for apex.

Why do certain dyes migrate toward the cathode and others towards the anode?
Molecules migrate to different electrodes depending on the charge they carry. Positively charged dyes migrate toward the anode (the negative electrode) and negatively charged dyes migrate toward the cathode (the positive electrode)

Short fragments travel more quickly toward the positive pole during gel electrophoresis. This is because smaller DNA fragments can move more easily through the pores of the gel matrix, leading to faster migration rates compared to larger fragments.
How does electrophoresis separate DNA based upon differences in size?
Electrophoresis is the motion of dispersed particles (like DNA fragments) relative to a fluid under the influence of a spatially uniform electric field. DNA electrophoresis is an analytical technique used to separate DNA fragments by size. DNA molecules which are to be analyzed are set upon a viscous medium, the gel, where an electric field forces the DNA to migrate toward the positive potential, the anode, due to the net negative charge of the phosphate backbone of the DNA chain. The separation of these fragments is accomplished by exploiting the mobilities with which different sized molecules are able to traverse the gel. Longer molecules migrate more slowly because they experience more drag within the gel. Because the size of the molecule affects its mobility, smaller fragments end up nearer to the anode than longer ones in a given period.

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.
What are three organisms that migrate toward the fertile Okavango delta?
Three organisms that migrate towards the fertile Okavango Delta are zebras, elephants, and wildebeests. They are attracted to the region for the abundance of water and lush vegetation that support their survival and reproduction.
Does gel electrophoresis seperate dna fragments?

One function of gel electrophoresis is to?
To separate strands of DNA based on their size. Shorter strands will migrate more slowly than larger strands. ** Also because DNA is slightly negatively charged, it will move toward the positive end of the electrodes... this is why the current is used when running a gel. Short strand move further** than large ones due to the gel resistance.
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.
