In minimal RNA kissing complexes formed between hairpins with cognate GACG tetraloops both tertiary GC pairs tend stabilized from the stacking of 5’-unpaired adenines at each end from the brief helix. adenines produced terminal pairs work similar to interior foundation pairs. The purine double-ring of adenine was needed for effective stacking whereas extra functional organizations… Continue reading In minimal RNA kissing complexes formed between hairpins with cognate GACG
