Analysis of oligo(deoxynucleoside phosphorothioate)s and their diastereomeric composition.

abstract：:An attempt has been made to correlate differential scanning calorimetry melting profiles of 5S rRNAs from lupin seeds (L.s.) and wheat germ (W.g.) with their structure. It is suggested that the observed differences in thermal unfolding are due to differences in RNA nucleotide sequence and as a consequence in higher or...
