How DNA marker length and migration distance?
discussion electrophoretic separation DNA ?
A short stretch of DNA that can be distinuished from other molecules due to radioisotope labeling is a a gene library b DNA sequencer c probe d DNA fingerprint?
c) probe. A probe is a short stretch of DNA labeled with a radioisotope or fluorescent marker that is used to identify the presence of specific DNA sequences in a sample.
How can a reporter enzyme monitor transformation of host cells by foreign DNA in addition to a selectable marker?
A reporter enzyme monitors transformation of host cells by foreign DNA in addition to a selectable marker through insertional inactivation. It differentiates recombinants from non recombinants.
What is the number of cuts in lamda DNA by Pst 1 enzyme?
I hope this will help you: http://www.sfusd.edu/programs/sf_base/protocols/lab_104_lambda.pdf Fun Fact: DNA stands for Deoxyribonucleic acid (But, you probably already knew that).
What is blue script plasmid?
Blue script plasmid is a type of cloning vector used in molecular biology for DNA cloning. It generally contains elements such as a bacterial origin of replication, a selection marker, and sites for restriction enzyme digestion for inserting foreign DNA. BlueScript plasmids are often used for routine cloning and sequencing purposes.
Which molecule for which phosphorus-32 is used as a radioactive marker?
Dna
What is the purpose of the ladder marker DNA?
DNA passes through a gel at different speeds depending on its size. The purpose of the ladder marker of a DNA is to make the passing of DNA possible.
Are the DNA molecules used for transformation of animal cell not require marker genes?
No
Do the DNA molecules used for the transformation of animal cells need marker genes?
yes
Why a ladder DNA marker is usually run in parallel with DNA samples separated by gel electrophoresis?
The ladder DNA marker is the reference to indicate the position of a particular resolved band according to the molecular weight. Once the gel is solved, the Rf of the bands can be estimated in reference to the ladder DNA marker.
How DNA marker length and migration distance?
discussion electrophoretic separation DNA ?
A specific marker with a single peak indicates that the individual is with respect to that particular STR marker?
A single peak for a specific STR marker indicates that the individual has two identical alleles at that particular locus. This information can be used in DNA profiling for identification and genetic testing purposes.
A short stretch of DNA that can be distinuished from other molecules due to radioisotope labeling is a a gene library b DNA sequencer c probe d DNA fingerprint?
c) probe. A probe is a short stretch of DNA labeled with a radioisotope or fluorescent marker that is used to identify the presence of specific DNA sequences in a sample.

What name is given to a region of DNA that varies from person to person?
A region of DNA that varies from person to person is called a polymorphic region or a polymorphism. These variations are responsible for the uniqueness and diversity observed among individuals.
How are DNa bands viewed?
DNA bands are usually visualized using techniques such as agarose gel electrophoresis or polyacrylamide gel electrophoresis. After electrophoresis, DNA bands can be viewed under UV light by staining the gel with a fluorescent dye, such as ethidium bromide. The DNA bands will appear as distinct bands of varying sizes depending on the migration pattern of the DNA fragments.
