In certain embodiments, the present invention provides a modified transfer RNA (tRNA) comprising a T-arm, a D-arm, and anticodon-arm and an acceptor arm, wherein the T-arm comprises nucleotides that interact with the elongation factor 1 alpha protein, and methods of use thereof. In certain embodiments, the present invention provides a modified transfer RNA (tRNA) comprising a T-arm, a D-arm, and anticodon-arm and an acceptor arm, (a) wherein the anticodon-arm comprises a tri-nucleotide anticodon, wherein the anticodon is 5'-UCA-3' and recognizes TGA stop codons, and wherein the acceptor arm isoperably linked to a arginine, tryptophan or glycine; (b)wherein the anticodon-arm comprises a tri-nucleotide anticodon, wherein the anticodon is 5'-UUA-3' and recognizes TAA stop codons, and whereinthe acceptor arm is operably linked to a glutamine or, glutamate; or (c) wherein the anticodon-arm comprises a tri-nucleotide anticodon, wherein the anticodon is 5'-CUA-3' and recognizes TAG stop codons, and wherein the accep
