The markers are of a specific size (in numbers of base pairs). By comparing the rates of migration of the various markers with the rates of migration of the gene/genes you are separating, you can get an estimate of the size of the fragments you are interested in. They also let you know if you need more or less separation. If the smaller fragments run off of the gel, you'll know that you need to run if for a shorter time or with a smaller voltage.

DNA fragments can be separated and analyzed by?
gel electrophoresis, a technique that uses an electric field to separate DNA fragments based on size. The smaller DNA fragments move faster through the gel, while larger fragments move more slowly. This allows researchers to determine the sizes of DNA fragments in a sample.
What is used to sort DNA into different lenghts?
Gel Electrophoresis
What is the technique that gel electrophoresis uses to separate and analyze DNA fragments based on their size and charge?
Gel electrophoresis separates and analyzes DNA fragments by passing an electric current through a gel matrix, causing the DNA fragments to move based on their size and charge.
How can gel electrophoresis be used to separate and analyze DNA fragments?
Gel electrophoresis separates DNA fragments based on size by applying an electric field to move them through a gel matrix. Smaller fragments move faster and travel further, allowing for analysis of DNA size and quantity.
Can DNA sequence be cut into smaller fragments by gel electrophoresis?
DNA cannot be cut into smaller fragments by gel electrophoresis. Gel electrophoresis is a technique used to separate DNA fragments based on size by applying an electric field to move them through a gel matrix. The DNA must be fragmented using restriction enzymes before running it on a gel for size separation.
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.

Are restriction enzymes used in gel electrophoresis?
For DNA gel electrophoresis, yes. Once the DNA is cut up into different-sized fragments, they can be electrophoresed to separate bands.
How can gel electrophoresis be used to separate and analyze DNA fragments?

What procedure is used to separate and analyze DNA fragments by placing a mixture of DNA fragments at one end of a porous gel and supplying an electrical voltage to the gel?
agarose gel electrophoresis
What is a technique for sorting DNA fragments by length?
Agarose gel electrophoresis is a common technique used to separate DNA fragments based on their size. In this method, DNA fragments are loaded into wells at one end of a gel and then subjected to an electric field, causing the fragments to migrate through the gel based on their size. The smaller fragments move faster and travel farther than larger fragments, allowing for sorting by length.
How are DNA fragments separated on DNA fingerprinting?
Gel electrophoresis
Can DNA sequence be cut into smaller fragments by gel electrophoresis?
DNA cannot be cut into smaller fragments by gel electrophoresis. Gel electrophoresis is a technique used to separate DNA fragments based on size by applying an electric field to move them through a gel matrix. The DNA must be fragmented using restriction enzymes before running it on a gel for size separation.
How does gel electrophoresis separate DNA by size?
Gel electrophoresis separates DNA fragments based on their size through an electric current. The negatively charged DNA molecules move towards the positively charged end of the gel. Smaller fragments move faster and migrate further through the gel than larger ones, resulting in the separation of DNA fragments by size.
Which fragment moves the furthest in gel electrophoresis?
Smaller DNA fragments move faster and further in gel electrophoresis compared to larger fragments. The distance migrated by DNA fragments in gel electrophoresis is inversely proportional to their size.
