  2. Pseudoknot - Wikipedia

    en.wikipedia.org/wiki/Pseudoknot

    The pseudoknot was first recognized in the turnip yellow mosaic virus in 1982. [2] Pseudoknots fold into knot-shaped three-dimensional conformations but are not true topological knots . These structures are categorized as cross (X) topology within the circuit topology framework, which, in contrast to knot theory, is a contact-based approach.

    A pseudoknot is a nucleic acid secondary structure containing at least two stem-loop structures in which half of one stem is intercalated between the two halves of another stem. Pseudoknots fold into knot-shaped three-dimensional conformations but are not true topological knots .

  4. Nucleic acid tertiary structure - Wikipedia

    The pseudoknot motif occurs when a single stranded region of a hairpin loop base-pairs with an upstream or downstream sequence within the same RNA strand. The two resulting duplex regions often stack upon one another, forming a stable coaxially stacked composite helix.

    en.wikipedia.org/wiki/Influenza_virus_pseudoknot

    The Influenza virus pseudoknot is an RNA pseudoknot structure formed in one of the non-structural coding segments (NS) of influenza virus genome. [1] Pseudoknots are commonly found in viral genomes , especially RNA viruses , where they incorporate an RNA splice site and can have a wide range of functions. [ 2 ]
