abstract：:Transfer RNAGlu4 was isolated from Drosophila melanogaster by affinity chromatography. The tRNA was iodinated "in vitro" with Na[25I] and hybridized "in situ" to salivary gland chromosomes from Drosophila. Subsequent autoradiography allowed the localization of the genes for tRNAGlu4 to the right arm of the second chro...
