The sugar-phosphate backbone forms the structural framework of nucleic acids, like DNA and RNA, and is composed of alternating sugar and phosphate groups.
The double-helical structure of DNA is an excellent scaffold for supramolecular design. The predictable formation of selective Watson-Crick base pairs and the easy introduction of chemically modified nucleotide building blocks have inspired the design of therapeutically important nucleic acids~([1, 2])...
Answer to: The nucleotides in the backbone of DNA are held together by ___ bond. A) Phosphodiester. B) Peptide. C) Hydrogen. D) Glycosidic...
The DNA double helix is the 'twisted ladder' shape in which DNA appears. A double helix is formed of two strands of DNA that are connected via hydrogen bonds. The shape of the DNA helix allows DNA to be stored, replicated, protected, and repaired. Answer and Explanat...
The Watson-Crick base-paired double helix can be observed in different conformations4-6, depending on humidity and salt concentration. Within the limited resolution of X-ray fibre diffraction at high relative humidity and in the appropriate salt conditions, studies indicate that natural DNA as well...
A、The two strands are parallel. B、Van der Waal's forces between stacked bases destabilizes the structure. C、The two strands are antiparallel. D、A, B, and Z-DNA forms are present in nature. E、Only the B-DNA form is present ...
circuitsat the heart of computers will be produced inexpensively in almost limitless quantities. The secret is that instead of silicon chips serving as the platform for electric circuits, computer engineers will take advantage of the unique properties ofDNA, thatdouble-helixcarrier of all life's ...
The features of Watson-Crick model are: A、double helix B、two DNA chains are antiparallel C、There are major groove and minor groove on the surface of DNA D、deoxyribose and phosphate constitute backbone E、left-handed helix

However, with α-helices, such a transformation would be expected to effect a change in the handedness of the helix and so mirror imaging would not ordinarily occur for single helices and all-helix protein structures, but rather, it would occur only with isolated helices in predominantly β-...
