The secondary structure of an RNA is formed by interactions between specific nonadjacent bases in the primary nucleotide sequence. The four canonical RNA bases, adenine (A), uracil (U), guanine (G), and cytosine (C), are paired through hydrogen bonds according to the Watson-Crick principle (...
This MTase function is associated with the nsp16 protein, which requires a cofactor, nsp10, for its proper activity. Here we show the crystal structure of the nsp10-nsp16 complex bound to the pan-MTase inhibitor sinefungin in the active site. Our structural comparisons reveal low conservation...
Base pairing of the nitrogen bases takes place according to Chargaff's rules. Purine (Adenine and Guanine) always base pairs with a pyrimidine (...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
Stem cells are one of the foundational evolutionary novelties that allowed the independent emergence of multicellularity in the plant and animal lineages. In plants, the homeodomain (HD) transcription factor WUSCHEL (WUS) is essential for the maintenance
True or false? Nucleotides within a single strand of DNA are connected by covalent bonds. The sugar in DNA is called ribose. True False DNA is double stranded, is located in the nucleus, and is composed of the base pairs adenine, uracil, guanine, and cytosine. True or...

Here we present a pulse scheme that allows such an observation and quantification of trans-hydrogen bond 3hJ(NC)' correlations in nucleic acid base pairs, between the imino nitrogen 15N1 and the carbonyl 13C6 nuclei within the guanine quartets of the Oxy-1.5 DNA-quadruplex. Intra- and ...
The “G” in the green box represents the guanine nucleotide. 2.1. Structural diversity of the catalytic subunits The catalytic subunit provides three functionalities to the archetypal CISM: (i) a molecular scaffold for the complex and highly labile Mo-bisPGD cofactor (Fig. 3); (ii) a substra...
Streptomyces are our principal source of antibiotics, which they generate concomitant with a complex developmental transition from vegetative hyphae to spores. c-di-GMP acts as a linchpin in this transition by binding and regulating the key developmental
