What is the Working principal of electrophoresis?
Separates DNA fragments so they can be seen
Which features of DNA fragments are used to separate them in the process of gel electrophoresis?
The separation is caused by the electrical direct current applied to the gel. Those molecules charged negatively will tend to go to the anode (positive) and those negatively charged migrate to the cathode.
How does DNA migrate in electrophoresis?
Electrophoresis is performed in a buffer solution with a static pH. An electric field is applied to the electrophoresis chamber containing a positive end and a negative end. If the pH of the substance being electrophoresed is lower than the surrounding buffer, it will migrate towards the positive end. If the substance has a pH higher than the surrounding buffer, it will migrate towards the negative end. Substances migrate at different rates based on two things: particle size, and overall charge. The greater the difference between the migrating substance's pH and the pH of the surrounding buffer, the faster that substance will migrate through the gel. Large molecules get "stuck" due to friction forces and migrate less rapidly than smaller particles that can navigate through the gel with very little resistance.
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 the pH does affect the separation of amino acids by electrophoresis?
The separation of amino acids by electrophoresis is influenced by the pH because it affects the ionization state of the amino acids. At different pH levels, amino acids can exist in different forms (protonated or deprotonated), which affects their charge. Amino acids with different charges will migrate at different speeds during electrophoresis, leading to their separation.

What is the opposite of migrate?
it is a movement of people and there is no opposite. Perhaps reside, or remain in situ could be used the opposite of immigrate is emigrate
Do female hammerhead sharks migrate different to male?
No they do the same thing, they migrate to warmer waters in the winter and the opposite in the summer

How do you migrate from heart- gold to ruby?
You can't migrate from HeartGold to Ruby. But it can be the opposite. Pokemon can be migrated from Pokemon Ruby to Pokemon HeartGold.
Why does sickle cell hemoglobin migrate slower than normal hemoglobin during electrophoresis?
because of the change of AA- in normal cell- from Glutamic acid (negativity charged) to Valine (uncharged) -in sickle cell- the charge will be missing in the sickle cell that why the electrophoresis will become slower because of the missing charge

How do you interpret electrophoresis?
In electrophoresis, DNA is subjected to an electric field which causes the genetic material to migrate in a direction from a cathode to an anode. The DNA that is closest to the anode is determined to be shorter in length compared to the DNA that is closer to the anode. This is explained by fact that the smaller fragments of DNA are better able to travel through the porous gel.
Gel electrophorysis and GMO food?
Gel electrophoresis is a method for separation and analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size and charge.The tool of DNA gel electrophoresis was developed in the 1970s. The process uses electricity to separate DNA fragments by size as they migrate through a gel matrix.It can be used to separate proteins that are used in genetically modified foods.

Which event occurs during metaphase?
chromosomes migrate to equator of the spindle apparatus
How does centrosome migrate to opposite pole?
The centrosomes run tubulin chains that form and act like little rails.
