Detailed explanation-1: -Restriction enzymes are also called “molecular scissors” as they cleave DNA at or near specific recognition sequences known as restriction sites. These enzymes make one incision on each of the two strands of DNA and are also called restriction endonucleases.
Detailed explanation-2: -Once electroporated into the nucleus of eukaryotic cells, restriction enzymes will bind at specific DNA sequences and cleave DNA to make double-strand breaks. These induced breaks can lead to chromosome aberrations and consequently offer one approach to determining the mechanism(s) of aberration formation.
Detailed explanation-3: -Restriction endonucleases are a family of enzymes that each cut DNA at a specific sequence recognition site, which may be rare or frequent in the DNA of the species being examined.
