What is Example of restriction enzyme?
A restriction enzyme (also known as restriction endonuclease) is protein which cuts DNA up at specific sequences (called restriction sites) in a genome. For example, the commonly used restriction endonuclease EcoRI recognizes every DNA sequence GAATTC and cuts at the point between the guanine and the adenine in that sequence, forming blunt ends (or straight, even ends). Interestingly and coincidentially, the restriction site for most restriction enzymes are genetic palindromes (the sequence reads exactly the same backwards on the complementary strand). In the case of EcoRI, the two complementary DNA strands for the restriction site are:5'-- GAATTC --3'3'-- CTTAAG --5'After this DNA sequence is cut, it might look something like this:5'-- G AATTC --3'3'-- C TTAAG --5'
What are restriction enzymes?
Restriction enzymes (also known as restriction endonucleases) are proteins which cut DNA up at specific sequences in the genome. For example, the commonly used restriction endonuclease EcoRI recognizes every point in DNA with the sequence GAATTC, and cuts at the point between the Guanine and Adenine. Interestingly, the recognition sequences for most restriction endonucleases are genetic palindromes, e.g., the sequence reads exactly the same backwards on the complementary strand. In the case of EcoRI, the two complementary DNA strands for the recognition sequence are: 5'--GAATTC ---3'3'--CTTAAG--5'
What type of molecule cut the gene from the DNA of an oraganism?
The type of molecule that cuts genes from DNA is typically a restriction enzyme, also known as a restriction endonuclease. These enzymes recognize specific sequences of nucleotides in the DNA and cleave the DNA at or near these sites. This ability allows scientists to manipulate DNA for various applications, including cloning, genetic engineering, and molecular biology research.
What cuts DNA into fragments?
Enzymes called restriction endonucleases, also known as restriction enzymes, are used to cut DNA into fragments at specific nucleotide sequences. These enzymes recognize and cut DNA at specific recognition sites, creating DNA fragments of different sizes. This process is commonly used in molecular biology for genetic engineering and DNA analysis.
How does restriction enzyme digest plasmid DNA?
Restriction enzymes, also known as restriction endonucleases, recognize specific sequences of nucleotides in plasmid DNA and cut the DNA at these sites. This digestion results in the generation of fragments with defined ends, which can be either blunt or sticky (overhanging) depending on the enzyme used. These fragments can then be used in cloning applications, allowing for the insertion of foreign DNA into plasmids. The precise cutting action of restriction enzymes is essential for various molecular biology techniques, including recombinant DNA technology.
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 could account for low endonuclease activity?
Low endonuclease activity could be due to improper folding or denaturation of the enzyme, suboptimal pH or temperature conditions for activity, or lack of cofactors required for enzymatic function. Additionally, mutations in the gene encoding the endonuclease enzyme could also lead to reduced activity.
What is the substance required to cleave the vector DNA during recombinant DNA technology?
Restriction enzymes are the substances required to cleave the vector DNA during recombinant DNA technology. These enzymes recognize specific DNA sequences and cut the DNA at specific points, allowing for the insertion of foreign DNA fragments.

What cuts DNA at a specific sequence of nucleotides?
Restriction enzyme cut the DNA at the specific site. Xho I is an example for restriction endonuclease which cut between C and T in the sequence of -CTCGAG- at the both strands. This is highly specific and hence they are used in DNA or gene cloning.

What is the role of BSA in restriction enzyme activity?
BSA is used to stabilize some enzymes during digestion of DNA and to prevent adhesion of the enzyme to reaction tubes and other vessels. This protein does not affect other enzymes that do not need it for stabilization.
What is GAATTC?
It is a sequence of DNA that is also a palindrom. i.e. the complimentary sequence of DNA would read the same way (but in the other direction). g a a t t c c t t a a g Moreover it is the sequence of DNA recognised by the restriction endonuclease EcoR1, the first such enzyme to be discovered. These enzymes have been important tools in science allowing pieces of DNA to be specifically excised and manipulated.

What is angiotensin-converting enzyme also called?
Serum Angiotensin-Converting Enzyme
What must researchers know before they begin the process of gentic engineering?
you need to know which restriction enzyme to use. also, who is the doner and the plasmid.
