What acts as a 'molecular scissors' in biotechnology?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Term "Molecular Scissors":** In biotechnology, the term "molecular scissors" refers to a tool or mechanism that can cut DNA at specific locations. This is crucial for genetic engineering and molecular cloning.

2. **Identifying the Enzyme:** The enzyme that functions as molecular scissors is known as a restriction endonuclease.

3. **Function of Restriction Endonuclease:** Restriction endonucleases are specialized enzymes that recognize specific nucleotide sequences in DNA and cleave the DNA at or near these sites. This allows scientists to manipulate DNA for various applications, such as cloning, gene editing, and creating recombinant DNA.
