Biotechnology uses restriction enzymes to cut DNA molecules at specific sequences.

Here's a breakdown:

* Restriction enzymes are proteins that act like molecular scissors. They recognize and cut DNA at specific short nucleotide sequences called restriction sites.

* Each restriction enzyme has a unique restriction site it targets.

* This specificity is essential for manipulating DNA in various applications, including:

* Gene cloning: Cutting and inserting genes into vectors for transfer.

* DNA fingerprinting: Identifying individuals based on unique DNA patterns.

* Gene therapy: Modifying genes to treat genetic diseases.

* Forensic science: Analyzing DNA evidence in criminal investigations.
