restriction endonuclease
What else can I help you with?
What molecule is used to find and cut DNA in genetic engineering processes?
The molecule used to find and cut DNA in genetic engineering processes is called a restriction enzyme.
Why restriction enzyme is also called endonuclease enzyme?
Because these enzymes cut the DNA molecule at a particular site. But like scissors these are useful tools in genetic engineering or recombinant DNA technology.
Which tool do biologist use to cut a section of DNA from a chromosome?
Restriction enzymes
What is the molecule used to cut the gene from the DNA in an organism?
Restriction endonuclease
When is DNA cut during electrophoresis?
Electrophoresis technique is not designed to cut DNA molecule. When DNA is analyzed by electrophoresis to determine its molecular mass, the molecular biology engineer usualy digests the DNA molecule, before the electrophoresis, with specific enzymes called "restriction enzymes" in order to obtain fragments of diverse molecular weights that can be seen as bands in electrophoresis gels.
When scientist copy DNA they first have to cut out the part they want to copy what molecule do they use to do this?
Restriction endonuclease.
When scientist copy DNA the first have to cut out the part they want to copy what molecule do they use to do this?
Restriction endonuclease.
When scientist copy DNA they first have to cut out the part they want to copy . What molecule do they use to do this?
Restriction endonuclease.

Restriction endonuclease
What will cut a DNA sequence only if it matches the sequence precisely?
A restriction enzyme will cut a DNA sequence only if it matches the specific recognition sequence of that enzyme. These enzymes are highly specific and will cleave the DNA at a particular site when the target sequence is present in the DNA molecule.
How do restriction enzymes specifically target and cut DNA molecules?
Restriction enzymes recognize specific sequences of nucleotides in DNA molecules, called recognition sites. These enzymes then bind to these sites and cut the DNA at specific points within or near the recognition site, resulting in the cleavage of the DNA molecule.
How many fragments of DNA would result from BamHI cut sites?
BamHI is a restriction enzyme that recognizes the specific DNA sequence "GGATCC" and cuts between the G and the A. The number of DNA fragments produced by BamHI cutting a DNA molecule depends on the number of BamHI recognition sites present in that molecule. Each recognition site will result in one additional fragment; thus, if there are n cut sites, the DNA will be divided into n+1 fragments.
