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. - [Read Rapid Amplification of 3' cDNA Ends 3'-RACE Protocol]
