RESUMO

Polyadenylated [poly(A)+] RNA has been isolated from the halophilic archaebacterium Halobacterium halobium by binding, at 4 degrees C, to oligo(dT)-cellulose. H. halobium contains approximately 12 times more poly(A) per unit of RNA than does the methanogenic archaebacterium Methanococcus vannielii. The 3' poly(A) tracts in poly(A)+ RNA molecules are approximately twice as long (average length of 20 nucleotides) in H. halobium as in M. vannielii. In both archaebacterial species, poly(A)+ RNAs are unstable.
