Major steps in completing gel electrophoresis?

Answer 1

1. There is a permeable gel with a row of holes on one side.

2. Different DNA samples are placed in holes using pipette.

3. An electric current is sent through the gel, with the opposite side as positive (the DNA is negatively charged).

4. Since the larger parts of DNA cannot get far through the gel and the smaller parts can. Several bands will be formed on the gel.

5. The bands are visible under UV light

6. These bands can be used to compare genetic similarity to determine the parent/sibling.

Answer 2

An improved discontinuous sodium dodecyl sulfate polyacrylamide electrophoresis process for measuring the migration of a macromolecule through the gel is disclosed. The improvement involves the use of thymol blue, phenol red, o-cresol red, orange G, m-cresol purple and mixtures, as a tracking dye.

Answer 3

Firstly knowing the electrophoresis wiil be better.

Electrophoresis is the phenomenon of migration of the charged particle under the influence of the electric field.

In gel electrophoresis, for instance: we take DNA, it is negatively charged and is loaded in the wells of the gel then the DNA will move towards the positivity and separate it on the basis of its density. it will move towards its opposite charge due to the electric current generated.

Answer 4

1) Add loading dye to desired sample(s).

2) Make a gel. Agarose gel, for example, is made by mixing agarose powder with buffer, heating until the powder has dissolved, adding ethidium bromide, pouring the mixture into a gel box, and putting in combs which are pulled out after the gel has cooled to make wells.

3) Make sure the wells are positioned so that the material that is being analyzed is has room to run. For example, since DNA is negative and runs towards to positive electrode, the wells are best off being positioned on the far negative side.

4) Add enough running buffer in the gel box to cover the gel.

5) Load sample(s) (a ladder is usually loaded as well).

6) Attach the electrodes to the power source.

7) Run for the designated amount of time.

8) After the gel has run, turn off the power source, remove the gel carefully and analyze using a UV light box.

Answer 5

The major steps in completing gel electrophoresis start with permeable gel with holes on a single side. Different DNA is placed in each hole via pipette. The gel then gets an electric current sent through it to positively charge the opposite side. This should create bands in the gel that can be seen under UV light. These are then used to compare similarities in genes to find parent/sibling relationships.

Answer 6

The method of gel electrophoresis is that it uses an electric curret passed through a gel medium to seperate nucleic acids of proteins. Small particles move easier than large particles, which gives a distinct pattern in the gel.

Answer 7

Electrical charge, angaros gel and buffer solution which allows the elecrical current to be conducted through the gel.
