The meaning of DOUBLE HELIX is a helix or spiral consisting of two strands in the surface of a cylinder that coil around its axis; especially : the structural arrangement of DNA in space that consists of paired polynucleotide strands stabilized by cross-
Watson and Crick's Double Helix Model Click the card to flip it 👆DNA is a thread-like molecule, made up of two long strands of nucleotides that are bound together in the shape of a double helix. If the helix were unwound, the molecule would look something like a ladder....

The crystal structure of the RNA dodecamer 5′-GGACUUUGGUCC-3′ has been determined from X-ray diffraction data to 2.6 Å resolution. This oligomer forms an asymmetric double helix in the crystal. Four consecutive non-Watson-Crick base-pairs are formed
A (double-stranded) DNA molecule is a helix formed by two polynucleotide chains running in opposite directions and held together by base pairing, either between an adenine and a thymine or between a guanine and a cytosine. From: Brenner's Encyclopedia of Genetics (Second Edition), 2013 ...
Biophysical and structural analysis revealed that 5fC alters the structure of the DNA double helix and leads to a conformation unique among known DNA structures including those comprising other cytosine modifications. The 1.4-Å-resolution X-ray crystal structure of a DNA dodecamer comprising three ...
The crystal structure of a dsRBD of Xenopus RNA-binding protein A in complex with dsRNA shows that dsRBD interacts with two successive minor grooves across the intervening major groove on one face of a dsRNA helix (Ryter and Schultz 1998). The N-terminal α-helix interacts with 2′OH and ...
which had been defined earlier. By definition, macrophages are classically activated in response to interferon-γ (IFN-γ) and lipopolysaccharide (LPS), and alternatively activated in response to IL-4 and IL-13 [8]. Over the years, with a greater understanding of macrophages, the implications ...
