Deoxyguanosine with attached phosphorous atoms is shown in the two major nucleic acid sugar puckers. The C2′ endo pucker (left) is found in B-DNA, whereas the C3′ endo pucker (right) is found in A-DNA or in RNA. The distance between successive phosphate groups is close to 7.0 A in C2′ endo and shortens to 5.8‐6 A in the C3′ endo pucker. Nucleic acids can convert from one pucker to the other, although it takes greater energy for conversion of ribonucleotides. Carbon, large open circles; hydrogen…

TLDR
Although DNA models based on fiber diffraction patterns led to an understanding of how sugar conformation affects the architecture of the double helix, single crystal diffraction studies of mini-helices [RNA] and oligonucleotides at high resolution later routinely allowed accurate visualization of the sugar pucker.
Ricin A-chain substrate specificity in RNA, DNA, and hybrid stem-loop structures.
TLDR
Mapping these interactions on the structure of GAGA stem-loop RNA suggests that all the loop 2'-hydroxyl groups play a significant role in the action of ricin A-chain.

Incorporating a Thiophosphate Modification into a Common RNA Tetraloop Motif Causes an Unanticipated Stability Boost.
TLDR
The consequences of replacing the SRL phosphate engaged in a face-on interaction with guanine with either PS2 or PSO for stability are investigated and it is found that PS2·G and Rp-PSO···G contacts stabilize modified SRLs compared to the parent loop to unexpected levels.
Why are Hoogsteen base pairs energetically disfavored in A-RNA compared to B-DNA?
TLDR
Insight is provided into a fundamental difference between A-RNA and B-DNA duplexes with important implications for how they respond to damage and post-transcriptional modifications.
Spontaneous Assembly of an Organic–Inorganic Nucleic Acid Z‐DNA Double‐Helix Structure
TLDR
A hybrid polyoxometalate organic–inorganic compound, Na2[(HGMP)2Mo5O15]⋅7 H2O (1; where GMP=guanosine monophosphate), which spontaneously assembles into a structure with dimensions that are strikingly similar to those of the naturally occurring left‐handed Z‐form of DNA.
Impact of modified ribose sugars on nucleic acid conformation and function
TLDR
This review article introduces the conformational properties of the (deoxy)ribofuranose ring and then explores sugar modifications and how they impact local and global structure and dynamics in nucleic acids.

TLDR
It is shown that single-crystal X-ray diffraction analysis made it possible to precisely define the RNA double helix, discover the novel L-shaped fold of transfer RNA (tRNA), and finally reveal the complete three-dimensional tRNA structure by 1974.

Three-Dimensional Structure of Yeast Phenylalanine Transfer RNA: Folding of the Polynucleotide Chain
TLDR
At 4 � resolution the polynucleotides in yeast phenylalanine transfer RNA are seen in a series of electron dense masses about 5.8 � apart, and it is possible to trace the entire polyn DNA chain with only two minor regions of ambiguity.
A crystalline fragment of the double helix: the structure of the dinucleoside phosphate guanylyl-3',5'-cytidine.
TLDR
The sodium salt of guanylyl-3',5'-cytidine crystallizes in a monoclinic unit cell with one molecule in the asymmetric unit with geometry very similar to those which have been derived from studies of fiber x-ray diffraction patterns of double-stranded RNA, even though the latter do not yield data at atomic resolution.

Negative supercoiling of plasmid DNAs containing 24--42 base pairs of alternating d(pCpG) inserts is shown to cause the flipping of the helical hand of the inserts from right to left under
Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid
TLDR
The determination in 1953 of the structure of deoxyribonucleic acid (DNA), with its two entwined helices and paired organic bases, was a tour de force in X-ray crystallography and opened the way for a deeper understanding of perhaps the most important biological process.
Crystal structure analysis of a complete turn of B-DNA
TLDR
This work reports the first single-crystal structure analysis of more than a complete turn of right-handed B-DNA, with the self-complementary dodecamer sequence d(CpGpCpC pGpApApTpTpCPGp CpG) or CGCGAATTCGCG.
Three-Dimensional Tertiary Structure of Yeast Phenylalanine Transfer RNA
TLDR
The 3-angstrom electron density map of crystalline yeast phenylalanine transfer RNA has provided us with a complete three-dimensional model which defines the positions of all of the nucleotide residues in the moleclule, which explains, in a simple and direct fashion, chemical modification studies of transfer RNA.
Double Helix at Atomic Resolution
The sodium salt of the dinucleoside phosphate adenosyl-3′,5′-uridine phosphate crystallizes in the form of a right handed antiparallel double helix with Watson-Crick hydrogen bonding between uracil
High-resolution x-ray diffraction patterns of crystalline transfer RNA that show helical regions.
TLDR
From an analysis of the packing in the unit cell it is concluded that the molecular dimensions are approximately 80 by 33 by 28 A, indicating that the double-helical portions of the transfer RNA molecule are approximately half a helical turn in length, and therefore can contain 4-7 base pairs.
