One Drosophila melanogaster tRNAGly gene occurs on each 1.1-2.0 kb unit of a direct duplication at chromosomal region 56F. The nucleotide sequence of the gene and the 5' flanking region has been determined. The non-transcribed strand sequence of the tRNA gene is: 5' GCATCGGTGGTTCAGTGGTAGAATGCTCGCCTGCCACGCGGGCGGCCCGGGTTCGATTCCCGGCCGATGCA 3'. This nucleotide sequence is identical to that of the major glycine tRNA in Bombyx mori posterior silk gland. Within the 22 kb region mapped, additional tRNA genes are found, an observation consistent with reports that genes for other isoacceptors are present at this locus.
在果蝇染色体区域56F的一个直接重复序列中，每1.1 - 2.0 kb单位存在一个黑腹果蝇tRNAGly基因。该基因及其5'侧翼区域的核苷酸序列已被确定。tRNA基因的非转录链序列为：5' GCATCGGTGGTTCAGTGGTAGAATGCTCGCCTGCCACGCGGGCGGCCCGGGTTCGATTCCCGGCCGATGCA 3'。此核苷酸序列与家蚕后部丝腺中主要甘氨酸tRNA的序列相同。在所定位的22 kb区域内，发现了其他tRNA基因，这一观察结果与该位点存在其他同功受体基因的报道一致。
