What are restriction enzymes and how are the names of restriction enzymes derived?
Restriction enzymes, also known as restriction endonucleases, are proteins that cut DNA at specific sequences, which are typically palindromic. Their names are derived from the organism they are isolated from, often including the genus, species, and a strain designation, followed by a roman numeral that indicates the order of discovery. For example, EcoRI comes from Escherichia coli (the genus and species) and was the first restriction enzyme isolated from that organism. These enzymes are crucial tools in molecular Biology for cloning, DNA manipulation, and genetic engineering.

What enzyme do scientists use to cut genes out of strands if DNA?
restriction 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.
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 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.
Bacterial proteins that cut DNA molecules at specific nucleotides are?
Restriction enzymes
Which enzyme opens DNA molecules?
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
