What is the function of amino-acyl-tRNA synthetase?

Explanation

**Step-by-Step Solution:**

1. **Definition of Amino-acyl-tRNA Synthetase**: Amino-acyl-tRNA synthetase is an enzyme also known as tRNA ligase. It plays a crucial role in protein synthesis.

2. **Function of the Enzyme**: The primary function of amino-acyl-tRNA synthetase is to attach the appropriate amino acid to its corresponding tRNA (transfer RNA). This process is essential for translating the genetic code into proteins.

3. **Mechanism of Action**: The enzyme catalyzes the reaction that links the amino acid to the tRNA. This is achieved through a process known as transesterification, where the enzyme facilitates the formation of a covalent bond between the amino acid and the tRNA.
