Originally restriction enzymes (RE) are isolated from Bacteria and Archaea. Microorganisms uses REs to protect themselves from the viral infection. For example EcoRI is isolated from E.colianbd BamHI is found in Bacillus amyloliquefaciens. With the advent of rDNA technology these enzymes are now being produced in lab organisms by cloning and expression.

What enzyme do scientists use to cut genes out of strands if DNA?
restriction enzymes
Are bacteria a source of restriction enzymes in DNA?
Restriction enzymes are made by the ribosomes in bacteria. For information on which bacteria produce which specific restriction enzymes, some can be found in a table near the bottom of this page: http://en.wikipedia.org/wiki/Restriction_enzymes
Do restriction enzymes cut protein molecules at specific sites?
No. restriction enzymes do not cut proteins. restriction enzymes cut DNA molecules at specific sites called restriction sites.
Which of the following cuts DNA molecules at specific locations?
restriction endonuclease enzymes
What does a geneticist use to cut DNA at specific base sequences?
Restriction enzymes, also known as restriction endonucleases, are used to cut DNA into smaller fragments. Restriction enzymes are found in bacteria, where they act like molecular scissors by cutting up DNA from invading viruses or bacteriophages. Each restriction enzyme recognizes a specific nucleotide sequence and cuts the DNA at that site. This process makes restriction enzymes extremely useful in biotechnology where they are used in procedures such as DNA cloning, DNA fingerprinting, and genetic engineering. There are hundreds of known restriction enzymes, and each one was named for the bacteria from which it was isolated. For example, EcoRI was isolated from Escherichia coli and HaeIII from Haemophilus aegyptius.
Which pair of enzymes is necessary to make recombinant DNA?
Actually the answer would be Restriction enzyme and DNA ligase.
Where restriction enzymes come from?
Restriction enzyme, also called restriction endonuclease, a protein produced by bacteria that cleaves DNA at specific sites along the molecule. In the bacterial cell, restriction enzymes cleave foreign DNA, thus eliminating infecting organisms.

Enzymes used to cut DNA molecules in recombinant DNA researsh are?
restriction enzymes
Do restriction enzymes cut protein molecules at specific sites?
No. restriction enzymes do not cut proteins. restriction enzymes cut DNA molecules at specific sites called restriction sites.
How are large DNA molecules cut up?
by using restriction enzymes
What are enzymes cutting DNA at specific sites to form restriction fragments called?
restriction enzymes or endonuclease enzymes
What is used to cut the DNA chain so that new genes may be inserted?
Restriction Enzymes
Which of the following cuts DNA molecules at specific locations?
restriction endonuclease enzymes
What organism uses restriction enzymes?
Bacterias use restriction enzymes as a form of defense mechanism. We as people use these restriction enzymes in bacterias to aid us in genetic engineering.
