Solution
The enzyme which acts as a biological scissors in genetic engineering is restriction endonuclease.
Explanation:
The enzyme that acts as biological scissors in genetic engineering is the restriction endonuclease. These enzymes cut DNA at specific sites, allowing the DNA to be fragmented for genetic manipulation. Restriction endonucleases are crucial in recombinant DNA technology for cutting DNA precisely to generate fragments containing identifiable genes. They are often referred to as “molecular scissors” or “chemical scalpels” because of this ability.
