Transfer RNA and aminoacyl-tRNA synthetases have been isolated from 5 day and 35 day old Drosophila melanogaster males. Transfer RNA isolated from old males cannot be aminoacylated to the same extent as tRNA from young flies. The average reduction is 16% and 53% for tRNALeu. The aminoacylation ability of some aminoacyl-tRNA synthetases isolated from 35 day old flies is reduced by more than 50%.
已从5日龄和35日龄的黑腹果蝇雄性个体中分离出转运RNA和氨酰-tRNA合成酶。从老龄雄性个体中分离出的转运RNA的氨酰化程度不如幼龄果蝇的tRNA。亮氨酸转运RNA（tRNALeu）的平均减少率分别为16%和53%。从35日龄果蝇中分离出的一些氨酰-tRNA合成酶的氨酰化能力降低了50%以上。
