What is the purpose of restriction enzymes in making recombinant DNA?
A restriction enzyme is an enzyme isolated from bacteria that cuts DNA molecules at specific sequences. The isolation of these enzymes was critical to the development of recombinant DNA (rDNA) technology and genetic engineering.
Why are restriction enzymes used in recombinant DNA?
Explanation: The restriction enzymes have the property of cleaving DNA molecules at a specific sequences. This restriction enzymes are used to cut DNA sequences at specific points of nucleotides. Some foreign genes are inserted into plasmids to make recombinant DNA.

What are the uses of restriction enzymes?
In the laboratory, restriction enzymes (or restriction endonucleases) are used to cut DNA into smaller fragments. The cuts are always made at specific nucleotide sequences. Different restriction enzymes recognise and cut different DNA sequences.
What is the role of restriction endonuclease?
The function of restriction endonucleases is mainly protection against foreign genetic material especially against bacteriophage DNA. The other functions attributed to these enzymes are recombination and transposition.
What is the purpose of restriction enzymes?
A restriction enzyme is an enzyme isolated from bacteria that cuts DNA molecules at specific sequences. The isolation of these enzymes was critical to the development of recombinant DNA (rDNA) technology and genetic engineering.
What are restriction enzymes used for?
Restriction enzymes can be isolated from bacterial cells and used in the laboratory to manipulate fragments of DNA, such as those that contain genes; for this reason they are indispensible tools of recombinant DNA technology (genetic engineering).
Why are restriction enzymes important in molecular biology?
The restriction enzyme prevents replication of the phage DNA by cutting it into many pieces. Restriction enzymes were named for their ability to restrict, or limit, the number of strains of bacteriophage that can infect a bacterium.
