INTRODUCTION
3'-RACE reactions are used to isolate unknown 3' sequences or to map the 3' termini of mRNAs onto a gene sequence. 3'-RACE requires knowledge of a small region of sequence within either the target RNA or a partial clone of cDNA. A population of mRNAs is transcribed into cDNA with an adaptor-primer consisting at its 3' end of a poly(T) tract and at its 5' end of an arbitrary sequence of 30-40 nucleotides. Reverse transcription is usually followed by two successive PCRs. The first is primed by a gene-specific sense oligonucleotide and an antisense primer complementary to the arbitrary sequence
