What is used to break apart dna fragments in a gel electrophoresis technique?

Labs typically use restriction enzymes.
'Restriction Enzymes cut DNA at specific recognition nucleotide sequences. To cut the DNA, a restriction enzyme makes two incisions, once through each sugar-phosphate backbone (i.e. each strand) of the DNA double helix.'
Meaning if you have a restriction enzyme that cuts at, say TA|GC, everywhere the TAGC sequence is in the DNA will be cleaved at that point. Because there are multiple instances of TAGC in the sample it leads to DNA fragments of differing sizes which then migrate at different rates under 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.
Why does extracted DNA need to be fragmented?
In preparation for the electrophoresis step in "DNA fingerprinting" the electrophoresis process cannot separate meaningfully massive molecules like whole chromosomes. By using restriction enzymes that break the chromosomes at known places DNA fragments of a wide variety of lengths that the electrophoresis process can separate meaningfully will allow a pattern to be generated that can identify different individuals.
What process can break rocks apart?
erosion can break rocks apart, weathering can also break rocks apart
Erosion can break rock into?
IgNeous actuallly its fragments
What heaps of frost-weathered rock fragments?
Heaps of frost-weathered rock fragments are known as scree or talus. They form when frost action causes rocks to fracture and break apart, creating a loose accumulation of debris at the base of cliffs or steep slopes. Scree can be found in mountainous and glaciated regions.

What is the dictionary meaning or denotation of the word crumbled?
The dictionary definition of "crumbled" is to break or fall apart into small fragments or pieces.
What is an advantage of working with short DNA fragments?
There are several advantages to working with short DNA fragments. These include being amplified better viaÊPCR technology, having better stability so that they do not break apart, and rarely degrading.
When did Pangea begin to break into smaller fragments?
Pagaea began to break apart about 180 million years ago during the Jurassic period.
