The language of nucleic acids is converted to the language of amino acids during the process known as

The information encoded by the genes on the DNA is copied into the single stranded RNA via the process of transcription. This transcripted single stranded m-RNA encoded the amino acid sequence of a protein. The ribosomes read these encoded sequence from the mRNA, and the tRNA brings the encoded amino acids to the ribosomes, which ultimately forms the protein. This process of conversion of the encoded information from the RNA (a nucleic acid) to amino acids is known as translation.

Thus, the language of nucleic acid is converted to the language of amino acids during the process is known as translation.
