What does a geneticist use to cut DNA at specific base sequences?

Answer 1

Restriction enzymes, also known as restriction endonucleases, are used to cut DNA into smaller fragments. Restriction enzymes are found in bacteria, where they act like molecular scissors by cutting up DNA from invading viruses or bacteriophages. Each restriction enzyme recognizes a specific nucleotide sequence and cuts the DNA at that site. This process makes restriction enzymes extremely useful in biotechnology where they are used in procedures such as DNA cloning, DNA fingerprinting, and genetic engineering. There are hundreds of known restriction enzymes, and each one was named for the bacteria from which it was isolated. For example, EcoRI was isolated from Escherichia coli and HaeIII from Haemophilus aegyptius.

Answer 2

Restriction enzymes can cut DNA at specific nucleotide sequences.

Answer 3

Biologists use enzymes called restriction endonucleases (or restriction enzymes) to cut DNA at specific sequences

Answer 4

restriction enzymes derived from bacteria cut DNA at specific DNA sequences. There are many restriction enzymes for cutting different sequences
