By simulating a Markov process comprising kinetically controlled elementary chain-growth steps and upstream refolding events, we compute the sequential folding of SV-11 RNA; a species capable of acting as a template instructing its own replication when folded into a metastable conformation. The predicted structure is endowed with available primers for… (More)
In this contribution we shall try to argue that no folding scenario - be it hierachical, nonhierarchical, nucleation, etc. - needs to be invoked to solve Levinthal's paradox: It fails on its own grounds.
It has been recently shown that the schedule of 3'-splicing events for yeast mitochondrial group I introns requires that conserved helix P10 materializes only after 5'-cleavage has taken place. A scenario compatible with experimental findings has been proposed [(1992) FEBS Lett. 297, 201-204; (1990) Proc. Natl. Acad. Sci. USA 87, 8192-8196] where the… (More)
We compute a metastable secondary structure for the cis antirepressor sequence (CAR) in the viral RNA of human immunodeficiency virus 1 (HIV-1) whose lifetime is long enough to allow for further stabilization by interaction with the ribosomal machinery. The structure emerges as the viral genome RNA is being synthesized by RNA polymerase II and corresponds… (More)
