NEET BIOLOGY

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: -Restriction enzymes are enzymes that have a specific restriction. For example, because the DNA strand is a lengthy strand, restriction enzymes are employed to cut the strand at specified locations. Eco RI, Bam H, and other molecular scissors are examples.

Detailed explanation-3: -The biologists use restriction enzymes to cut sections of DNA from one organism and transfer it to another. This allows molecular biologists to create hybrid DNA that has the best properties of both organisms. This technique has variety of uses in everyday medicine, including producing insulin, antibiotics and fuel.

Detailed explanation-4: -Examples of molecular scissors are Eco RI, Bam H etc. restriction enzymes are of two types based on their cleaving patterns-endonucleases and exonucleases.
