What is gel electrophoresis used for?

Answer 1

used to separate macromolecules, either nucleic acids or proteins, on the basis of size, electric charge, and other physical properties.

Separating strands of DNA

Answer 2

It is a good separation method for both proteins and nucleotides. (Different type of gels, though) It allows to separate different compounds to analyse what a sample contains, and it is possible to cut out gel fragments for further usage, thus using gel separation as a tool for isolation.

Answer 3

Gel electrophoresis can be used for separating DNA, RNA or proteins based on size. The larger molecules will move slowly through the gel and end up closer to the origin (the place where samples are loaded) and the smaller molecules are found closer to the terminal end of the gel.

Answer 4

Electrophoresis technology is use for separation technique that involving electrical charge interaction. The positively charge electrode will attract the negative charge compound/substance while the negatively charged electrode will attract the positive charge compound/substance. One of electrophoresis application is in analysis of Recombinant DNA product where the fragments want to be analyzed based on its size.

Answer 5

To separate and analyze DNA fragments and protein fragments by weight. If you have digested some bacterial DNA, for instance, then you can tell by running the fragmented DNA in the gel whether you have digested the correct base length.

Answer 6

Gel electrophoresis is a very general term and many different types of gels can be run with this technique. It is used by anyone wishing to look at DNA/RNA/Protein so generally biologists.

Answer 7

For profiling of proteins as per their molecular weight and rf values

Answer 8

Separating strand of DNA -
