The function of tRNA is to :

Options

A. synthesize amino acids
B. transcribe the genetic code
C. form a site for protein synthesis
D. transport specific amino acids to specific sites on the mRNA

Explanation

**Step-by-Step Solution:**

1. **Understanding tRNA**: tRNA stands for transfer RNA. It is one of the types of RNA involved in the process of protein synthesis.

2. **Role in Protein Synthesis**: The primary function of tRNA is to facilitate the synthesis of proteins by transferring specific amino acids to the ribosome, where proteins are assembled.

3. **Mechanism of Action**: tRNA molecules carry amino acids to the ribosome, which is the site of protein synthesis. Each tRNA is specific to one amino acid and recognizes the corresponding codon on the mRNA strand.

4. **Binding to Amino Acids**: Each tRNA molecule binds to a specific amino acid and transports it to the ribosome. For example, a tRNA carrying the amino acid phenylalanine will bring it to the ribosome when the corresponding codon on the mRNA is present.

5. **Formation of Polypeptide Chain**: As tRNA molecules bring amino acids to the ribosome, these amino acids are linked together in a specific sequence to form a polypeptide chain, which ultimately folds into a functional protein.

6. **Conclusion**: Therefore, the function of tRNA is to transfer a specific amino acid to a specific site on the mRNA during the process of translation in protein synthesis.

**Final Answer**: The function of tRNA is to transfer a specific amino acid to a specific site on the mRNA during protein synthesis.
