[RNA secondary structure dynamics and genetic vector symmetry]

The sequence of nucleotides in a single-stranded RNA molecule is represented by a complex vector, whose k-th component corresponds to the k-th base of the sequence ordered in the 5'3' direction. An analysis of the proposed formalisms permits to predict a new type of reversible conformational transitions between the secondary structure patterns of RNA which may have an oscillatory character. A possible experimental approach based on the ESR technique for recording and time-scale estimation of these transitions is proposed.
