title: Hamster mitochondrial transfer RNA lacks T and the universal GUUCG sequence.
abstract: Earlier inferences (based on incorporation of radio-activity from methyl-labeled methionine) that mammalian mitochondrial tRNA lacks ribothymidine ('T') have been confirmed using [14C]uridine as precursor. Moreover, oligonucleotide fingerprint analysis of 32P-labeled samples have shown that hamster mitochondrial tRNA lacks the 'universal' pentanucleotide of conventional tRNA in which T normally occurs, CTpsiCG, in modified or unmodified form.
