The electricity pulls the polar DNA strands through the gel, and shorter DNA strands move farther because they are less inhibited by the gel. The gel acts as drag to separate the different length DNA strands, so different DNA creates specific dye bands.

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.
Is agarose gel electrophoresis suitable for only gram negative plasmid DNA?
Agarose gel electrophoresis is suitable for ALL DNA.
What is a common name for gel electrophoresis?
Agarose gel electrophoresis.
Function of agarose in agarose gel electrophoresis?
Agarose is used in gel electrophoresis to separate nucleic acids (like DNA) by size, charge an other physical properties. Gel electrophoresis uses an electrical current to make particles move. For example, DNA is negative, so it'll travel towards to positive electrode of the gel box. Agarose has small pores through which a DNA can travel. Bigger fragments of DNA travel shorter distances, because it takes longer for them to navigate through the pores of the agarose gel. Identically sized pieces of DNA will travel the same distance, which is why you get bands (DNA with loading dye) after you run a a gel.
What gel is typically used in electrophoresis experiments?
The gel typically used in electrophoresis experiments is agarose gel.

What is role of agarose of electrophoresis?
Agarose is used in gel electrophoresis as a medium to separate DNA fragments based on their size. When an electric current is passed through the agarose gel, DNA molecules move through it at different speeds, allowing for separation by size. Agarose forms a matrix that acts as a sieve, slowing down larger DNA fragments more than smaller ones.
What is the functions of UV transilluminator in genetic laboratory?
to vizualise DNA after Agarose gel electrophoresis
What is the function of agarose gel electrophoresis?
Agarose gel electrophoresis is used to separate DNA fragments based on size. When an electric current is applied to the gel, DNA molecules move through the pores of the gel at different rates depending on their size, allowing for visualization and analysis of DNA fragments in a sample.
What is the principle for agarose gel electrophoresis?
Agarose gel electrophoresis is based on the principle that DNA molecules are negatively charged and will migrate towards the positive electrode in an electric field. The smaller DNA fragments move faster through the agarose gel matrix, allowing for separation based on size. UV light is commonly used to visualize the separated DNA bands after electrophoresis.
what is the gel in Gel Electrophoresis?
The gel in gel electrophoresis is typically made of agarose or polyacrylamide. It acts as a matrix to separate DNA, RNA, or proteins based on size and charge as an electric current passes through it. Agarose gels are commonly used for DNA analysis, while polyacrylamide gels are often used for higher resolution protein separation.
