Electrophoresis technique is not designed to cut DNA molecule. When DNA is analyzed by electrophoresis to determine its molecular mass, the molecular biology engineer usualy digests the DNA molecule, before the electrophoresis, with specific enzymes called "restriction enzymes" in order to obtain fragments of diverse molecular weights that can be seen as bands in electrophoresis gels.
DNA samples are within the gel matrix during electrophoresis. DNA moves at differtent rates through the pores of the gel depending on how long the fragments are. DNA is held by the gel itself.
Separates DNA fragments so they can be seen
Inert electrodes simply serve as electrical conductors and are unchanged by the cell processes. Active electrodes change during the cell reactions. An example of inert electrodes is platinum in the electrolysis of water. The platinum remains unchanged and the water is split into hydrogen and oxygen. An example of active electrodes is in the electrolysis of copper sulfate solution with copper electrodes. The anode copper is converted into copper ions in the solution, and metallic copper builds up on the cathode. The term active electrode is also used in eeg measurement, here as the opposite to passive electrode. Electrodes are the pads attached to the skin to get readings, and active ones don't need a conductive paste to get a good signal.
when using the micropipettes,be careful and avoid contaiinating the micropipettes by slowly releasing the plunger

The smallest and lightest fragments.

IGNITION ELECTRODES IMPLIES TWO ARE INSTALLED. TWO ELECTRODES IMPLIES AN OIL FIRED BOILER. THE ELECTRODES ARE TIED ELECTRICALLY TO THE SECONDARY WINDINGS OF A HIGH VOLTAGE TRANSFORMER. DURING IGNITION THE TRANSFORMER PRODUCES A SPARK BETWEEN THE ELECTRODES TO IGNITE THE ATOMIZED MIXTURE THAT THE BURNER MOTOR AND OIL PUMP PRODUCE AND DELIVER VIA THE NOZZLE. LC
Yes, by keeping the PC plugged in during the non-use can really damage the computer.

In traditional "lead-acid" batteries, the electrodes are lead and lead (IV) oxide. During discharge, both electrodes dissolve in the strong acid electrolyte to form dissolved lead (II) cations. During recharge, these reactions are reversed. Other battery types, with a longer rechargeable life are used for hybrid electric-gasoline cars.
1. WHAT IS ELECTROPHORESIS AND WHAT ARE THE IMPORTANTAPPLICATIONS OF ELECTROPHORESIS?Ans. Movement of charged particle in the electric field either towards cathode or anode whensubjected to an electric current is called electrophoresis.The following factors influence the movement of particles during the electrophoresis.(a) Electric current.(b) Net charge of the particle.(c) Size and shape of the particle.(d) Type of supporting media.(e) Buffer solution.Important Applications of ElectrophoresisThe technique of electrophoresis is used to separate and identify the(i) Serum proteins(ii) Serum lipoproteins(iii) Blood hemoglobins2. WHAT ARE THE DIFFERENT TYPES OF ELECTROPHORESIS?Ans. (a) Moving boundary electrophoresis: This technique was first introduced by TISELIUS in 1937(b) Zone electrophoresis: In this type of electrophoresis different types of supporting mediaare used. These are;(a) Paper electrophoresis(i) Whatman filter paper(ii) Cellulose acetate(b) Gel electrophoresis(i) Agarose.(ii) Polyacrylamide gel (used for the separation of isoenzymes).(iii) SDS-PAGE.(iv) Iso-electric focussing (proteins seperated in a medium possessing a stable pH gradient).(v) Immuno electrophoresis (for the separation of immunoglobulins).
They are negatively charged and are of different sizes
please display a diagram of lead placement
They shouldn't. When using the correct electrode and amperage they will get hot but not red hot. Uncoated electrodes do get red hot but are not used in most applications. Too much amperage is usually the problem.
