Restriction enzymes are produced by bacteria to help destroy foreign, invading DNA, such as the DNA of bacteriophage (a virus that infects bacterial cells). Every restriction enzyme comes with a methylase enzyme, or more specifically, a DNA methyltransferase. The methylase enzyme methylates (adds a methyl group) to the restriction endonuclease site on the cell's own DNA, which protects the sites from the restriction enzyme so that it does not degrade its own DNA.
What else can I help you with?
Which restriction enzyme did you use to cut the DNA?
The restriction enzyme used to cut the DNA was EcoRI.
Where does the restriction enzyme EcoRI cut in a DNA sequence?
The restriction enzyme EcoRI cuts DNA at a specific sequence of bases, which is GAATTC.
What enzyme do scientists use to cut genes out of strands of DNA?
Scientists use an enzyme called restriction enzyme to cut genes out of strands of DNA.
What is the difference between a restriction enzyme and an endonuclease?
A restriction enzyme is a type of endonuclease. Endonucleases are enzymes that cut DNA at specific sequences, while restriction enzymes specifically cut DNA at recognition sites called restriction sites.
Where in the DNA sequence does the restriction enzyme EcoR1 specifically cut?
The restriction enzyme EcoR1 specifically cuts the DNA sequence at the recognition site GAATTC.
Which restriction enzyme did you use to cut the DNA?
The restriction enzyme used to cut the DNA was EcoRI.
Where does the restriction enzyme EcoRI cut in a DNA sequence?
The restriction enzyme EcoRI cuts DNA at a specific sequence of bases, which is GAATTC.
What enzyme do scientists use to cut genes out of strands if DNA?
restriction enzymes
What enzyme do scientists use to cut genes out of strands of DNA?
Scientists use an enzyme called restriction enzyme to cut genes out of strands of DNA.
Where do they cut the DNA strand?
They direct a specific Restriction Enzyme to cut the Dna Exactly where required.
What is the difference between a restriction enzyme and an endonuclease?
A restriction enzyme is a type of endonuclease. Endonucleases are enzymes that cut DNA at specific sequences, while restriction enzymes specifically cut DNA at recognition sites called restriction sites.
Where in the DNA sequence does the restriction enzyme EcoR1 specifically cut?
The restriction enzyme EcoR1 specifically cuts the DNA sequence at the recognition site GAATTC.
Which enzyme do scientist use to cut genes out of strands of DNA?
restriction endonuclease
Which enzyme do scientist use to cut out strands of DNA?
They are called restriction enzymes and there are all sorts depending on the sequence of DNA they are trying to cut
What is the best explanation for why a restriction enzyme does not cut the DNA of the cell that produces it?
Restriction enzymes are made by cells to protect their own DNA from being cut. These cells produce a modification enzyme that adds a methyl group to specific sites on their own DNA sequence, which prevents the restriction enzyme from cutting. This process is known as "methylation protection."
What enzyme cuts and seals DNA?
The enzyme that cuts DNA is called a restriction enzyme, while the enzyme that seals DNA is called DNA ligase. Restriction enzymes cut DNA at specific sequences, creating breaks in the DNA strands, while DNA ligase seals these breaks by catalyzing the formation of phosphodiester bonds between the DNA fragments.
What determines how DNA will be cut by a restriction enzyme?
Restriction enzymes cut DNA at specific sites called restriction sites. These restriction sites are typically 6 - 8 nucleotides in length and have a defined set of nucleotide bases. For example, the restriction enzyme Eco R1 cuts at the site: AGGTTC. Therefore, if the target DNA contains the above sequence, Eco R1 is able to cut it within the restriction site. Hence, by looking into the target site and which restriction enzymes are being used, on can make an accurate estimate of where the target DNA will be cut
