Gel electrophoresis is a process by which molecules based on size, charge length etc can be separated. Using an electric field, molecules (such as DNA) can be made to move through a gel made of agarose or polyacrylamide. The electric field consists of a negative charge at one end which pushes the molecules through the gel, and a positive charge at the other end that pulls the molecules through the gel.
Shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through the pores of the gel. This phenomenon is called sieving.
Similarly a negetive charged molecule will be pushed away while a positive charged particle will not.

NA fingerprinting uses a process called gel electrophoresis to separate the fragments of DNA. Once the DNA fragments are sorted, the pattern of bands can be analyzed. 1)Gel Electrophoresis Procedure The smaller DNA fragments start to move away from the wells and the larger DNA fragments remain closer to the wells. 2)An electric current is passed through the gel. 3) DNA fragments are treated with a dye. 4)A restriction endonuclease is added to the DNA. 5)Using micropipettes, the DNA samples...

In the nuclease digestion experiment, the scientists use a technique called gel electrophoresis. While this is related to SDS-PAGE used in the separation of membrane proteins, it is NOT THE SAME thing. From the list below, choose all the ways that gel electrophoresis is done for nuclease digestion is different from the gel electrophoresis in SDS-PAGE. Group of answer choices 1.Used to separate DNA or RNA. 2.Used to separate proteins. 3.Prteins and DNA must be separated prior to running the...

What is the purpose of gel electrophoresis? How is size related to movement through a gel? What is a DNA ladder? Why is it important in gel electrophoresis and how is it used? (note: a ladder is also called a “standard”) What are two indications one can look for to be certain the gel electrophoresis is occurring? What are two strategies to improve the resolution of DNA bands?
Briefly explain how 2D-gel electrophoresis works and specify what types of molecules it detects.

Gel electrophoresis. Polypeptides can be separated by electrophoresis according to their relative content of acidic and basic residues. The isoelectric point (pI) of a polypeptide is the pH at which its net charge is zero. (See Fig 3.11 of your textbook). A) At physiological pH (= 7.4), what is the net charge on the tripeptide Asp-Arg-Glu-His? B) Calculate the pI of this tetrapeptide. [Hint: Using the pK, values in Table 2.1 and the Henderson-Hasselbalch equation, determine the pH when the...

3. Application of DNA gel electrophoresis. DNA gel electrophoresis is commonly used in determining familial relationships among individuals, for ex; to establish paternity of a child. This technique is called DNA fingerprinting. In this technique the DNA of parents and children is roughly chopped up into pieces and resolved on an agarose gel. The DNA ill resolve according to their sizes and create a pattern or a "fingerprint". The fingerprint of the child is...
