WebMay 19, 2024 · The FSS is an RNA hairpin or a pseudoknot ( Atkins et al., 2001 ). The slippery sequence allows cognate pairing of the P-site and A-site tRNAs in both 0 and −1 frames and thus makes frameshifting thermodynamically favorable ( Bock et al., 2024 ). The mechanism by which FSS stimulates frameshifting is less clear. WebHairpin structure is a pattern that can occur in single-stranded DNA or, more commonly, in RNA.
