Pseudoknot - Biological Significance

Biological Significance

Several important biological processes rely on RNA molecules that form pseudoknots, which are often RNAs with extensive tertiary structure. For example, the pseudoknot region of RNase P is one of the most conserved elements in all of evolution. The telomerase RNA component contains a pseudoknot that is critical for activity, and several viruses use a pseudoknot structure to form a tRNA-like motif to infiltrate the host cell.

Famous quotes containing the words biological and/or significance:

    Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.
    Betty Rollin (b. 1936)

    Of what significance the light of day, if it is not the reflection of an inward dawn?—to what purpose is the veil of night withdrawn, if the morning reveals nothing to the soul? It is merely garish and glaring.
    Henry David Thoreau (1817–1862)
