Triplex Structures
This non-Watson-Crick base-pairing allows the third strands to wind around the duplexes, which are assembled in the Watson-Crick pattern, and form triple-stranded helices such as (poly(dA)•2poly(dT)) and (poly(rC)•2poly(rC)). It can be also seen in three-dimensional structures of transfer RNA.

Famous quotes containing the word structures:
“It is clear that all verbal structures with meaning are verbal imitations of that elusive psychological and physiological process known as thought, a process stumbling through emotional entanglements, sudden irrational convictions, involuntary gleams of insight, rationalized prejudices, and blocks of panic and inertia, finally to reach a completely incommunicable intuition.”
—Northrop Frye (b. 1912)
