title: The calculation of plant 5S rRNAs secondary structure.
abstract: Using commercially available computer software package for ribonucleic acid (RNA) secondary structure analysis we calculated the free energy (delta G) of all higher plant 5S rRNA species. To gain insight into the relation between structure (nucleotide sequence) and free energy we generated point mutants of plant 5S rRNA and calculated their secondary structure. This analysis permitted to identify single sites which affect the stability and conformation of RNA molecule. Furthermore, the calculated data were compared with the electrophoretic mobility of 5S rRNA on polyacrylamide gels.
