DNA fragments for gel electrophoresis can be obtained by breaking open cells (cell lysis) and isolating the DNA through methods like phenol-chloroform extraction or column purification. The DNA can then be cut into fragments using restriction enzymes or other methods before being loaded onto the gel for separation based on size.

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.
How are DNA fragments separated on DNA fingerprinting?
Gel electrophoresis
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.
Process that restriction fragments of DNA are separated from each other by the use of electricity?
The process you are referring to is called electrophoresis. In this technique, DNA fragments are loaded onto a gel matrix and an electric current is applied. The negatively charged DNA molecules move towards the positive electrode, separating based on size and charge.
What is the pattern of dark bands on photographic film that is made when DNA fragments are separated by gel electrophoresis and tagged?
The pattern of dark bands on photographic film in gel electrophoresis of DNA fragments is called a gel electrophoresis pattern. The dark bands are formed by DNA fragments of different sizes that have been tagged with a fluorescent or radioactive marker. The position of the bands indicates the size and quantity of the DNA fragments.

What is used to sort DNA into different lenghts?
Gel Electrophoresis
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.
What do the bands in gel electrophoresis represent?
The bands in gel electrophoresis represent different sizes of DNA fragments.
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 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.
What do the multiple bands in gel electrophoresis represent?
The multiple bands in gel electrophoresis represent different sizes of DNA fragments.
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.

The dark bands are formed by DNA fragments of different sizes that have been tagged with a fluorescent or radioactive marker. The position of the bands indicates the size and quantity of the DNA fragments.
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.
