In other organisms, # AGA/AGG code for either arginine or serine and in vertebrate # mitochondria they code a STOP. Evidence for glycine translation of # AGA/AGG has been found in Pyura stolonifera (Durrheim et al. 1993), # Halocynthia roretzi (Kondow et al. 1999, Yokobori et al., 1993, # Yokobori et al. 1999) and Ciona savignyi (Yokobori et al. 2003). In # addition, the Halocynthia roretzi mitochondrial genome encodes an # additional tRNA gene with the anticodon U*CU that is thought to enable # the use of AGA or AGG codons for glycine and the gene has been shown to # be transcribed in vivo (Kondow et al. 1999, Yokobori et al. 1999).
