Salvage enzymes in nucleotide biosynthesis [PDF]
, 2007 Balanced pools of deoxyribonucleoside triphosphates (dNTPs), the building blocks of DNA, and ribonucleoside triphosphates (NTPs), the precursors of RNA, are crucial for a controlled cell proliferation.

Hachimoji DNA and RNA: A genetic system with eight building blocks [PDF]
, 2019 Reported here are DNA and RNA-like systems built from eight (hachi-) nucleotide letters (-moji) that form four orthogonal pairs. This synthetic genetic biopolymer meets the structural requirements needed to support Darwinism, including a polyelectrolyte ...

Chemical and Pharmaceutical Bulletin, 1970 Adenosine 5'-phosphate was converted to the 2', 3'-cyclic phosphate by the treatment with dimethylformamide at reflux temperature. The reaction was shown to be proceeded by the initial release of the phosphoryl group as an"activated phosphoric acid"and rephosphorylated to furnish the 2', 3'-cyclic phosphate. In fact a ribonucleoside and phosphoric acid,

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Macromolecular Materials and Engineering, EarlyView.Alginate dialdehyde (ADA)‐gelatin (GEL) hydrogels are supplemented with mesoporous bioactive glass nanoparticles (MBGNs) and human platelet lysate (HPL) to enhance the biological performance of 3D printed scaffolds. Improved printability and higher shape fidelity are observed by incorporating 0.1% (w/v) MBGNs.

An Unusual Mode of DNA Duplex Association: Watson-Crick Interaction of All-Purine Deoxyribonucleic Acids [PDF]
, 2007 SummaryNucleic acid duplexes associating through purine-purine base pairing have been constructed and characterized in a remarkable demonstration of nucleic acids with mixed sequence and a natural backbone in an alternative duplex structure.

Optical Probes for Cellular Imaging of G‐quadruplexes: Beyond Fluorescence Intensity Probes
Angewandte Chemie, Volume 137, Issue 22, May 26, 2025.DNA and RNA can fold into tetra‐stranded helical structures known as G‐quadruplexes (G4s). There is mounting evidence suggesting that these structures have important biological roles. In this minireview we discuss advances in the design of optical probes for the detection of G4s that offer intensity‐independent readouts that address limitations of ...

Incorporation of Histamine Ribonucleoside into Soluble Proteins [PDF]
Nature, 1966 ISOTOPICALLY labelled histamine ribonucleoside can be detected in the urine of experimental animals after intraperitoneal administration of either 2(ring)−14C-labelled histamine1, or similarly labelled histamine-adenine-dinucleotides2. However, in such experiments the quantities of histamine ribonucleoside recovered from the urine represent only a ...

Plant, Cell &Environment, EarlyView.ABSTRACT Deep sequencing of ribosome footprints, also known as ribosome profiling (Ribo‐seq), enables the quantification of mRNA translation and a comprehensive view of the translatome landscape. Here, we report an optimised Ribo‐seq protocol and analysis pipeline for the model green alga, Chlamydomonas reinhardtiii (Chlamydomonas).
