Transfer RNA identity.

This is the authors' abstract. We don't add key points for this paper.

Since its theoretical inception, the tRNA molecule has been identified and many of its functions have been described in terms of its structure. However, the molecular basis for the aminoacylation specificity of tRNA has remained largely unsolved until recently, when substantial progress has disclosed fundamental aspects of this process. What we know and would like to know about tRNA identity will be outlined, as will the experimental approaches used in this research.
