A protein molecule in an electrophoresis gel has a negative charge. The exact charge depends on the pH of the solution, but 30 excess electrons is typical. What is the magnitude of the electric force on a protein with this charge in a 1400 N/C electric field? Express your answer in newtons.

Biologists use gel electrophoresis to sort DNA segments by size. DNA segments are placed at one end of a gel. DNA is negatively charged (with a charge of two electrons per base pair). When you “run the gel” you are generating an electric field by connecting anodes and cathodes at the ends of the gel. This causes the negatively charged DNA segments to move towards the positive electrode. After running the gel, smaller DNA segments have moved farther from the...

Protein molecules in solution can be separated from each other by taking advantage of their net charges. In the electric field between two electrodes, a positively charged particle moves toward the negative electrode and a negatively charged particle moves toward the positive electrode. This movement, known as electrophoresis, varies with the strength of the electric field, the charge of the particle, the size and shape of the particle, and the buffer/polymer gel combination through which the protein is moving. The...

3. Sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis a. After pouring the SDS polyacrylamide gel, you realize that instead of 2 ml, you used 4 ml of 30% acrylamide/bisacrylamide solution for the preparation of the separating gel (in both cases for 5 ml, total gel volume). How would this affect the separation of your proteins during SDS PAGE? Explain your answer! b. You have to remake the gel and are now making sure just to add...

An electric field can induce an electric dipole in a neutral molecule (or atom) by pushing the positive and negative charges inside the molecule in opposite directions. The dipole moment of the induced dipole is directly proportional to the electric field at the molecule. That is, p⃗ =αE⃗ , where p⃗ is the induced dipole moment, α is called the polarizability of the molecule, and E⃗ is the electric field at the molecule. A stronger electric field at the molecule results in a...
