Transfer RNA (tRNA) is a crucial component of the translation process in gene expression. It acts as an adaptor molecule, linking messenger RNA (mRNA) sequences to the corresponding amino acids during protein synthesis. The structure and function of tRNA are highly specialized, ensuring accurate decoding of genetic information.

### Structure of tRNA
tRNA has a distinct cloverleaf secondary structure and a compact L-shaped tertiary structure, which enables it to interact with ribosomes and enzymes efficiently. The primary structure consists of a single RNA strand of about 70–90 nucleotides. The main structural regions of tRNA include:
