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.
Restriction enzymes are produced by bacteria as a defense mechanism against invading viruses. Common sources of restriction enzymes include species such as Escherichia coli, Bacillus subtilis, and Haemophilus influenzae.
Bacteria for protection against viruses synthesize restriction enzymes which cut only viral without giving any harm to bacterial DNA.

What enzyme do scientists use to cut genes out of strands if DNA?
restriction enzymes
Are bacteria a source of restriction enzymes in DNA?
Yes, bacteria are a source of restriction enzymes. These enzymes are part of the bacterial defense system against foreign DNA, like that of phages or plasmids. They recognize specific DNA sequences and cut the DNA at those sites.
Do restriction enzymes cut protein molecules at specific sites?
No, restriction enzymes cut DNA molecules at specific sites. They recognize specific sequences of nucleotides in DNA and cleave the phosphate backbone at those points. Proteins are not typically cut by restriction enzymes.
Which enzyme opens DNA molecules?
Restriction Enzymes
Bacterial proteins that cut DNA molecules at specific nucleotides are?
restriction enzymes.
Which pair of enzymes is necessary to make recombinant DNA?
Restriction enzymes and DNA ligase are necessary to make recombinant DNA. Restriction enzymes are used to cut the DNA at specific sequences, while DNA ligase is used to join together pieces of DNA from different sources.
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.
What enzyme do scientists use to cut genes out of strands if DNA?
restriction enzymes
Are bacteria a source of restriction enzymes in DNA?
Yes, bacteria are a source of restriction enzymes. These enzymes are part of the bacterial defense system against foreign DNA, like that of phages or plasmids. They recognize specific DNA sequences and cut the DNA at those sites.
What are enzymes cutting DNA at specific sites to form restriction fragments called?
Enzymes that cut DNA at specific sites to form restriction fragments are called restriction endonucleases or restriction enzymes. These enzymes recognize specific DNA sequences and cleave the DNA at or near these sequences, generating DNA fragments with defined ends.
Do restriction enzymes cut protein molecules at specific sites?
No, restriction enzymes cut DNA molecules at specific sites. They recognize specific sequences of nucleotides in DNA and cleave the phosphate backbone at those points. Proteins are not typically cut by restriction 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.
Bacterial proteins that cut DNA molecules at specific nucleotides are?
restriction enzymes.
Which enzyme opens DNA molecules?
Restriction Enzymes
What does a geneticist use to cut DNA at specific base sequences?
A geneticist uses restriction enzymes to cut DNA at specific base sequences. These enzymes recognize specific DNA sequences and cleave the DNA at those sites, allowing researchers to manipulate and study genetic material.
Is topoisomerases belong to restriction enzymes?
No, topoisomerases are not the same as restriction enzymes. Topoisomerases are enzymes that regulate the supercoiling of DNA, while restriction enzymes recognize specific DNA sequences and cleave them. Both enzymes play different roles in DNA metabolism.
How are restriction enzymes important tools in genetic engineering?
restriction enzymes are important tools in genetic engineering because they just are!!
