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.

What enzyme do scientists use to cut genes out of strands if DNA?
restriction enzymes
Which pair of enzymes is necessary to make recombinant DNA?
Actually the answer would be Restriction enzyme and DNA ligase.
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.
What is the enzyme function of restriction enzymes?
We believe the function of the restriction enzyme is to protect an organism from foreign DNA as restriction enzymes cleave DNA strands (making them useless). The idea is that bacteria use this to protect against viral infection as viruses attach to the cell and insert their DNA into it in order to "take over" the cell. Restriction enzymes recognize this DNA as foreign and begin to chop it up, saving the cell.
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
What is the cutting of DNA by specific enzymes known as restriction endonucleases the cut piece from one organism is added to the DNA of another?
GE
Which of the following cuts DNA molecules at specific locations?
restriction endonuclease enzymes
What are the uses of restriction enzymes in biotechnology?
Restriction enzymes or endonucleases are like cutting enzymes fro DNA These are used to cut nucleotides at particular sites These have imp use in gene cloning,gene mapping,gene sequencing then applied techniques such as southern blotting These are extracted from bacteria's
What organisms make restriction enzymes?
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.
