What do you use to cut DNA strands for DNA fingerprints?
A Retsriction enzyme endonuclease is an enzyme that is used to cut DNA strands (both single and double strands) during finger printing at the DNA recognition sites known as restriction sites.
How are restriction enzymes used to look for differences between DNA samples?
Restriction enzymes cleave, or open, the DNA so that a sample can be taken and gel electrophoresis can separate the strands of DNA. From there, DNA probes bind to certain strands in each sample and DNA fingerprints can show the differences.
Can Restriction Enzymes be used on all DNA?
Restriction enzymes cut DNA at sites called restriction sites on the DNA. These restriction sites are specific sequences of 6 - 8 nucleotide bases. Restriction enzymes can be used on all types of DNA. If the DNA is cut by a certain restriction enzyme, then we know that the DNA contained the restriction site. This sort of an experiment is called restriction site analysis
Why is DNA sometimes called the fingerprint inside your body?
because everyone has different DNA and different fingerprints.
What enzyme do scientists use to cut genes out of strands if DNA?
restriction enzymes
Who has DNA fingerprints that are similar to your DNA fingerprints?
1 in 10,000,000
How are restriction maps used?
They are used to show the lengths of DNA fragments between restriction sites in a strand of DNA.
How do restriction sites and a restriction map relate?
Restriction maps show the lengths of DNA fragments between restriction sites in a strand of DNA.

What method is used to make DNA fingerprints?
A method known as RFLP (restriction fragment length polymorphism) analysis can be used to make a DNA fingerprint.

Do fingerprints provide DNA?
Fingerprints do not provide DNA themselves. It is the DNA that creates the contours of your fingerprints, so rather than providing the DNA fingerprints merely support it. Therefore, if DNA is already available it can easily be linked to fingerprints.

Under what circumstances are DNA fingerprints used?
In most cases DNA fingerprints are used in identifying crime suspects. If there are fingerprints left at a crime scene then DNA fingerprints are used to attempt to identify the suspect. There is a database of criminal fingerprints that prints can be matched to if they are in the database.
