Abstract Bep mRNAs are localized at the animal pole of P.
lividus eggs. In the present communication the secondary studied because only recently three maternal mRNAs, called
structures of the 3PUTRs of the bep1, bep3 and bep4 mRNAs bep1, bep3 and bep4, asymmetrically distributed in P. lividus
are reported. The minimal lenghts of these regions required to egg have been identi¢ed [9,10]. These messengers encode for
