title: Asymmetric linker molecules for recombinant DNA constructions.
abstract: Asymmetric EcoRI DNA linkers consisting of an AATTC(A)7 dodecamer and a complementary G(T)7 octamer were synthesized. Ligation of such linkers to DNA fragments obviates the need for EcoRI digestion prior to cloning in EcoRI-cleaved vectors.
