In this short renew unique conformational possibilities of polyadenylic acid are described. The possibility of double oligo(A)-helices formation in RNA biological systems has been discussed. It is proposed that the basis for stabilization effect of ELAV-like proteins is their ability to form internal double oligo(A)-helices in the poly(A) tails of specific mRNAs
