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
How DNA fragments are sorted by sized?
Electrophoresis
What is allelic ladder?
An allelic ladder is a set of DNA fragments with known sizes used as a reference in gel electrophoresis to estimate the size of unknown DNA fragments. It helps in determining the size of DNA fragments based on their migration distance in the gel relative to the ladder's fragments. This is commonly used in DNA fingerprinting and genetic analysis.
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 is the function of a DNA ladder in gel electrophoresis and how does it aid in the analysis of DNA fragments?
In gel electrophoresis, a DNA ladder serves as a reference for determining the sizes of DNA fragments being analyzed. It contains DNA fragments of known sizes, which help in estimating the sizes of unknown DNA fragments by comparison. This aids in accurately identifying and analyzing the DNA fragments present in the sample.

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.

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.
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 is the purpose of the ladder in gel electrophoresis and how does it help in analyzing DNA fragments?
The ladder in gel electrophoresis serves as a reference for determining the sizes of DNA fragments. It contains DNA fragments of known sizes, which help in estimating the sizes of unknown DNA fragments being analyzed. This allows researchers to accurately determine the size and compare the DNA fragments present in the sample.
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 do the bands in gel electrophoresis represent?
The bands in gel electrophoresis represent different sizes of DNA fragments.
What is used to sort DNA into different lenghts?
