What else can I help you with?
What enzyme do scientists use to cut genes out of strands if DNA?
restriction enzymes
Where do restriction enzymes originate from?
Restriction enzymes originate from bacteria.
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
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.
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 type of macromolecule are restriction enzymes classified as?
Restriction enzymes are classified as proteins, which are a type of macromolecule.
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.
Do restriction enzymes only recognize palindromic sequences?
No, restriction enzymes can recognize and cut sequences that are not palindromic.
How have scientists made bacteria more useful today?
Scientists have taken restriction enzymes out of bacteria; restriction enzymes are used to cut DNA at cut sites. Also, they insert genes into bacteria to study them.
Bacterial proteins that cut DNA molecules at specific nucleotides are?
Restriction enzymes
Which enzyme opens DNA molecules?
Restriction Enzymes
