DNA can be fragmented using restriction endonucleases or restriction enzymes. Restriction enzymes identify specific sequences within the DNA and cause cleavage generating fragments. When this digested DNA is allowed to run in gel electrophoresis fragments get separated according to their mass. When visualized under UV transilluminator, fragmented DNA can be observed as fluorescing bands.

After DNA is cut with a restriction enzymes how is the mixture of DNA fragments sorted?
Through the process of gel electrophoresis.
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.
What cuts DNA into fragments?
cutting of DNA into fragments simply means application of suitable restriction enzyme to it.now a days two types of restriction enzymes are available,1)exonucleases,which cut at end portion of DNA and 2)endonucleases ,which cut at specific inner site.
What does the charge of DNA have to do with DNA fingerprinting?
DNA is of a negative charge. So when gel electrophoresis is used on it the DNA fragments are attracted to the positive end of the electrophoresis. The fragments of different lengths travel down the gel towards this end. The longer length fragments travel less and so are farther from the positive end. By looking at these DNA fragments, which are created by cutting DNA with restriction enzymes one can compare and contrast DNA. Thus DNA fingerprinting can take place based on the different restriction sites in DNA (cut by the enzymes) forming different length segments of DNA.
How many lambda DNA fragments does BamHI make?
There are five BamHI cut sites in lambda DNA: Location 5505 22346 27972 34499 41732 So, BamHI will digest lambda DNA into six fragments.

What chemicals are used to cut DNA into fragments?
The chemicals used to cut DNA fragments are restriction endonucleases, eg- Eco R I, Eco R II,etc

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 are the cleaved DNA fragments from two sources able to recombine?
Sometimes, when the cleaved DNA fragments both have sticky ends, they naturally anneal due to complementary base pairing. However, an enzyme called DNA Ligase is used for joining cut strands of DNA together. There is a ligase called t4 Ligase that joins blunt ends because it is stronger.
Can DNA sequence be cut into smaller fragments by gel electrophoresis?
electrophoresis takes segments of DNA that are already broken up and aligns them by length with an electric current. It doesn't cut the DNA.Added:No, they must be cut into smaller pieces by restriction enzymes ( HINDI, for instance ) before they are run in the gel.
What is used to cut the DNA into fragment so its sequence could be read?
the process is called gel electrophoresis.
If you took a linear piece of DNA and cut it with the restriction enzyme EcoRI and it had three restriction sites for EcoRI, how many fragments would you produce What if you had a circular piece of DNA?
If the plasmid has 3 recognition sequences for a given restriction endonuclease, then 4 linear DNA fragments are obtained because, if the DNA is linear then the number of fragments obtained is (N+1) whereas if the DNA is circular then the number of fragments obtained will be N for N recognition sequences for the given restriction endonuclease in a plasmid.
Where does the wastage of diamond goes?
Diamond fragments separated from a diamond stone during the cutting process are collected and used to cut and polish other diamonds.
