Double helical forms of poly (A): possible involvement in biological processes

M. I. Zarudnaya

In this short renew unique conformational possibilities of polyadenylic acid are described. The possibility of double oligo(A)-nelices 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)-hetices in the poly(A) tails of specific mRNAs
