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)
“To grasp the full significance of life is the actor’s duty, to interpret it is his problem, and to express it his dedication.”
—Marlon Brando (b. 1924)
