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 gel is typically used in electrophoresis experiments?
The gel typically used in electrophoresis experiments is agarose gel.
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.
Why is gel used in electrophoresis and what purpose does it serve in separating molecules based on size and charge?
Gel is used in electrophoresis to create a matrix through which molecules can move. The gel serves to slow down the movement of molecules based on their size and charge, allowing for separation based on these characteristics.
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 used to sort DNA into different lenghts?

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 was used before gel electrophoresis?
Before gel electrophoresis, techniques like paper electrophoresis and agarose slab gel electrophoresis were used for separating and analyzing DNA or proteins. These methods were less efficient and had lower resolution compared to gel electrophoresis.
Difference between vertical and horizontal gel electrophoresis?
Horizantal gel electrophoresis is generally used for RNA/DNA based studies, while vertical gel electrophoresis is used for protein based studies.

Gel Electrophoresis
One lane of an electrophoresis gel shows a 100bp ladder. What is the purpose of this ladder?
It is used as a marker for molecular weight.
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.
Can gel electrophoresis be used to separate and analyze proteins?
Yes, gel electrophoresis can be used to separate and analyze proteins based on their size and charge.
What is the purpose of the holes at one end of the gel?
The holes at one end of the gel are used to load the DNA or protein samples for electrophoresis, allowing them to enter the gel and separate based on size. The samples are loaded into these wells using a pipette or a loading buffer before the electrophoresis process begins.
