Electrophoresis refers to the movement of charged particles in a fluid or gel under the influence of an electric field. It is carried out in buffer in order to complete the electron circuit flow.

What is the buffer solution and why is it added to the agarose?
You use a buffer when making agarose gels so that when the gel is used for electrophoresis, the gel is able to conduct electricity. The buffer contains ions from the buffer salts that will facilitate conduction. that was good
Why you need buffer solution to mix with unboiled yeast?
you dont
What is the purpose of gel electrophoresis?
The buffer is the medium through which the current flows. In the electrophoresis chamber, the anode and cathode are separated and the gel is placed between them. In order to close the circuit and generate the voltage which causes the migration, the entire chamber is filled with a conductive buffer. It is actually possible to perform electrophoresis without a buffer; however this requires a specially made electrophoresis chamber. In these chambers the electrodes actually contact the top and bottom of the gel eliminating the need for a conductive buffer to close the circuit.SDS PAGE electrophoresis uses buffer not primarily as a conductor but for holding a desired pH, dissipating heat and providing SDS in excess in the case of denaturing gels. A gel would run without a buffer as the gel itself is a conductor but the currents involved would heat it to the point of decomposition. Also the volume of liquid in a gel does not allow for an adequate pH buffering system. Holding a pH is extremely important for reproducibility especially in native gels as the pH can change the charge on the peptide. It is true some gels do not require buffer but these are rare cases like isoelectric focusing.the primary application of the buffer would be to conduct electricity,to form a closed circuit
Can be mixed in a solution with H2CO3 to make a buffer?
H2CO3 is not used as buffer.
How you classify the solution as a best buffer solution?
A buffer solution is one involving a weak base/weak acid with its conjugate acid/base. In a buffer solution, the pH must be changed to only a small amount. Thus, any solution with a STRONG acid or a STRONG base is not a successful buffer solution because there would be a relatively large change in the initial pH.
What is the function of buffer in the gel electrophoresis?
TBE buffer in gel electrophoresis is used to maintain pH of te solution and prevents the denaturation of smale fragments of DNA.
Are loading buffer and electrophoresis buffer the same thing?
Yes, yes they are.

A solution that is resistant to change in pH?
Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
What is pseudo buffer?
a solution which does not fulfills the property of a buffer solution but act as buffer solution.
Why you need buffer solution to mix with unboiled yeast?
you dont
What happens when HCl is mixed with a solution that is not a buffer solution?
If the solution is not a buffer, the HCl will react with the solution to form a product.
Why do you add iron III chloride buffer to the salicylate solution?
because you need to
What factors can classify electrophoresis techniques?
nature of the buffer, volume,nature of supporting material the format

What can destroy buffer solution?
The buffer solution is destroyed if the amount of acid or base that can be absorbed is exceded.
How do you prepare 50mM TES buffer?
In order to prepare 50mM TES buffer, you will need to add in approximately 1000 ml of Proteinase K solution. From there, you will need to separate and stack the gels.
