Abstract Base sequences of many transfer RNA (tRNA) species obtained from different sources contain homologous regions. These homologies, which are 6 to 20 nucleotides long, occur both within the same tRNA molecule and between many different tRNA molecules repeatedly. Since it is very unlikely an 80 or so nucleotide long tRNA molecule could have been formed at once, under primordial conditions, we propose that the homologous oligonucleotides found within the tRNA molecules to-day represent the earliest adapter from which tRNA molecules have evolved.
