title: Non-random frequencies of short oligonucleotide sequences within poliomyelitis and encephalomyocarditis virus RNAs.
abstract: In poliomyelitis and encephalomyocarditis virus RNAs the relative frequencies of several short oligonucleotide sequences differ substantially from those expected on a random basis. The frequencies of CpGp-containing sequences are low, and the frequency of GpUpApGp is considerably lower than that of GpApUpGp. The relationship of these findings to those obtained from host cell RNAs is descussed.
