Restriction endonucleases are enzymes found in bacteria and archaea. They are part of the bacteria's defense mechanism against invading foreign DNA, such as viruses, by cutting it into smaller fragments. These enzymes are widely used in molecular Biology for techniques like gene cloning and DNA fingerprinting.

An enzyme that cuts double-stranded DNA at specific nucleotide sequences?
This enzyme is called a restriction enzyme. They are commonly used in molecular biology to create DNA fragments with specific ends that can be ligated together.
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.
Poly nucleotides are cleaved at recognition sites within the strands by?
enzymes known as restriction endonucleases. These enzymes recognize specific nucleotide sequences and cleave the DNA at those sites. This process is often used in molecular biology for tasks such as gene cloning and DNA sequencing.
What is a DNA restriction site?
A DNA restriction site is a specific short nucleotide sequence recognized by a restriction enzyme, which cuts the DNA at that site. These sites are often palindromic, meaning the sequence reads the same forwards and backwards. Restriction sites are commonly used in molecular biology for DNA manipulation and analysis.
When scientists copy DNA they first to cut out the part they want to copy what molecules do they use to do this?
Scientists use restriction enzymes to cut out the specific part of DNA they want to copy. These enzymes recognize and cut DNA at specific sequences, allowing researchers to isolate the desired section for replication.
What is the molecule used to cut the gene from the DNA in an organism?
Restriction endonuclease
Do eukaryotes have restriction endonuclease?
no
Which enzyme do scientist use to cut genes out of strands of DNA?
restriction endonuclease

restriction endonuclease
What is the enzyme that opens up DNA?
restriction endonuclease and exonuclease
