Electrophoresis technique is not designed to cut DNA molecule. When DNA is analyzed by electrophoresis to determine its molecular mass, the molecular Biology engineer usualy digests the DNA molecule, before the electrophoresis, with specific enzymes called "restriction enzymes" in order to obtain fragments of diverse molecular weights that can be seen as bands in electrophoresis gels.

Scientists use gel electrophoresis to cut dna at a specific nucleotide True or false?
It is true that Scientists use gel electrophoresis to cut DNA molecules at a specific sequence of nucleotides.
After DNA is cut with a restriction enzymes how is the mixture of DNA fragments sorted?
Through the process of gel electrophoresis.
What holds the DNA sample during electrophoresis?
DNA samples are within the gel matrix during electrophoresis. DNA moves at differtent rates through the pores of the gel depending on how long the fragments are. DNA is held by the gel itself.
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 is a technique for sorting DNA fragments by length?
it is called " electrophoresis"

It is true that Scientists use gel electrophoresis to cut DNA molecules at a specific sequence of nucleotides.
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.
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.

Why you do electrophoresis?
electrophoresis is the process of putting dyed DNA that has been cut by enzymes into a gel substance in order to seperate the DNA for genetic ID. It can be used for paternity testing comparing DNA of the child to the father.
Which of the following can be used to cut DNA so it can be studied?
Restriction Enzymes is what they use.
How does gel electrophoresis is used to make a DNA fingerprint?
Gel electrophoresis separates DNA fragment on the basis of their size. In DNA fingerprinting or DNA typing given sample is cut up with restriction enzymes and run through electrophoresis and results are analyzed to check for DNA polymorphism between the given sample and a sample form suspect. In nutshell gel electrophoresis is boon for the people in forensics.
What is used to cut the DNA into fragment so its sequence could be read?
the process is called gel electrophoresis.
What is used to separate DNA fragments by size?

What is the role of EtBr in electrophoresis?
Ethidium bromide interchalates with DNA. It doesn't affect electrophoresis, but it help visualise the DNA bands after electrophoresis. The EtBr that is bound to the DNA will fluoresce under ultraviolet light.
What is used to sort DNA into different lenghts?
Gel Electrophoresis
