What is the function of allele ladder in DNA profiling?
An allele ladder is used as a reference for determining the sizes of DNA fragments in a sample during DNA profiling. It contains known fragments of DNA of varying sizes that are used to calibrate the gel electrophoresis results, allowing for accurate comparison and identification of the sizes of DNA fragments in the sample.
What is the function of allelic ladder?
An allelic ladder is a mixture of DNA fragments of known sizes that are used as a reference to estimate the size of DNA fragments in a sample by gel electrophoresis. It helps in determining the sizes of unknown DNA fragments by comparing their migration distances to those of the fragments in the allelic ladder on the gel.
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.
What is an allele ladder and what is its function in DNA profiling?
An allele ladder is a mixture of DNA fragments of known sizes used as a reference in DNA profiling. It helps determine the size of unknown DNA fragments by comparing them to the ladder's known sizes. This allows for accurate identification of the alleles present in a sample for forensic or paternity testing purposes.
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 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.
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.
Can the size of a supercoiled plasmid DNA be determined by using standard DNA fragments electrophoresed in parallel?
Yes, the size of a supercoiled plasmid DNA can be estimated by running standard DNA fragments with known sizes in parallel on an agarose gel. By comparing the migration distance of the supercoiled plasmid with the standard DNA fragments, an approximate size can be determined.

How can one determine the size of DNA fragments from electrophoresis?
One can determine the size of DNA fragments from electrophoresis by comparing the distance the fragments have traveled in the gel to a standard marker with known fragment sizes. The smaller fragments will travel farther while larger fragments will travel a shorter distance. This allows for estimation of the size of the DNA fragments based on their migration pattern.
Cutting DNA with a particular restriction enzyme produces?
DNA fragments with specific sizes depending on the recognition sequence of the enzyme. This process is used in molecular biology to create DNA fragments for analysis, manipulation, or recombinant DNA technology applications. The resulting fragments can be visualized on an agarose gel.
What form of technology uses electricity to sort DNA fragments based on their sizes?
gel electrophorsis

What do the bands in gel electrophoresis represent?
The bands in gel electrophoresis represent different sizes of DNA fragments.
