Ribonucleic acids (RNAs) consist of linear arrays of bases, some of which have the hydrogen-bonding capacity to interact with others to form base pairs. In addition to the standard Watson–Crick base pairings, RNAs have unusual base pairings that give rise to the many tertiary structures that ...
1.This paper adopts MP2(M ller-Plesset Perturbation Theory) quantum chemical method to research two modified base pairs in RNA.本文采用了二级微扰MP2理论的量子化学研究方法,对RNA中修饰碱基对2,4-二氟苯(B)和4-氟苯并咪唑(D),以及2,4-二氟苯(B)和4,6-二氟苯并咪唑(E)的相互配对进行了研究。
The pair of nitrogen-containing bases, consisting of a purine linked by hydrogen bonds to a pyrimidine, that connects the complementary strands of a DNA molecule or of hybrid molecules joining DNA and RNA. The base pairs are adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and ...

All base pairs in the genome are replicated during the DNA synthesis phase of the cell cycle, but only some of the base pairs are transcribed into RNA. How is it determined which base pairs of the genome are transcribed into RNA? 在细胞周期的DNA合成期,基因组中所有的碱基对都被复制,但只有...
The thermodynamic stabilities and structures of a series of RNA duplexes containing nonsymmetric tandem mismatches in the context of , where are tandem mismatches, were studied by UV melting and imino proton NMR. The contribution of one mismatch to the free energy increment for tandem mismatch forma...
Base pair, in molecular biology, two complementary nitrogenous molecules that are connected by hydrogen bonds. Base pairs are found in double-stranded DNA and RNA, where the bonds between them connect the two strands, making the double-stranded structure
Base Pairs RNA and DNA share many similarities, including the fact that they have four nucleotide bases that pair together. In DNA, adenine pairs with thymine and guanine pairs with cytosine. However, there is no thymine in RNA, and another base replaces it. ...

The NMR chemical shifts of the base protons in ten oligo-RNA duplexes 5,12–18 have been determined. We have now adjusted the helix winding angle, W , between adjacent base pairs (see Fig. 1 a ) to fit these data. There is extensive overlap of the hydrophobic surfaces of the bases ...
