What is the purpose of power supply in gel electrophoresis?
The power supply in gel electrophoresis is used to provide an electrical current that helps move charged molecules through the gel. By applying a voltage across the gel, DNA, RNA, or proteins migrate towards the opposite electrode based on their size and charge. This allows for the separation and analysis of molecules based on their molecular weight.
What is a common name for gel electrophoresis?
Agarose gel electrophoresis.
What is used to separate DNA fragments by size?
Electrophoresis. Restriction enzymes are used to cut DNA into fragments. Solutions containing these fragments are placed on the surface of a gel to which an electric current is applied. The electric current causes the DNA fragments to move through the gel. Because smaller fragments move more quickly than larger ones, this process separates the fragments according to size.
What is a technique that can be used to separate molecules in a mixture by subjecting them to an electrical field within a gel?
Gel electrophoresis is a technique that can be used to separate molecules in a mixture by subjecting them to an electrical field within a gel matrix. The molecules move through the gel at different rates based on their size and charge, allowing for their separation and analysis.
Which process is used to separate molecules by movement due to size and electrical charge?
Gel electrophoresis is the process used to separate molecules based on size and electrical charge. In gel electrophoresis, an electric field is applied to move charged molecules through a gel matrix. Smaller molecules move faster and migrate further than larger molecules, allowing for separation based on size and charge.

What is the purpose of the marker in gel electrophoresis?
The purpose of the marker in gel electrophoresis is to help determine the size of DNA fragments by providing known reference points for comparison.
What is the gel used for in gel electrophoresis?
The gel used in gel electrophoresis is a porous material that helps separate DNA, RNA, or proteins based on their size and charge when an electric current is applied.
What is the purpose of the gel used in gel electrophoresis?
The purpose of the gel used in gel electrophoresis is to separate and analyze DNA fragments based on their size. The gel acts as a sieve, allowing smaller fragments to move faster through the gel than larger fragments, resulting in distinct bands that can be visualized and studied.
What is the purpose of using a buffer in agarose gel electrophoresis?
The purpose of using a buffer in agarose gel electrophoresis is to maintain a stable pH and provide ions that help conduct electricity, allowing the DNA or other molecules to move through the gel.
What is a common name for gel electrophoresis?
Agarose gel electrophoresis.

Where do you place the DNA samples on the gel during electrophoresis?
During electrophoresis, DNA samples are placed at the wells of the gel. The gel is then subjected to an electric current, causing the DNA fragments to move through the gel based on their size.

What gel is typically used in electrophoresis experiments?
The gel typically used in electrophoresis experiments is agarose gel.
