含氮碱基(nitrogenous base):与1号碳原子连接,DNA的4个碱基是cytosine (C), guanine (G), adenine (A) 和 thymine (T),RNA中有U (Uracil),没有T。G、A属于嘌呤(purine),双环结构;C、T、U属于嘧啶(pyrimidine),单环结构。 五碳糖(pentose sugar):DNA中是脱氧核糖(deoxyribose),RNA中是核糖(ribose) 磷...
The three-dimensional structure of a pyrimidine-purine-pyrimidine DNA triplex containing an N7-glycosylated guanine (7G) in the third strand has been determined by NMR spectroscopy, restrained molecular dynamics calculations, and complete relaxation matrix refinement. Glycosylation of the guanine at the ...

7.1 Structure of DNA 7.1.1 Describe the structure of DNA, including the antiparallel strands, 3' -5' linkages and hydrogen bonding between purines and pyrimidines. DNA is made up of two strands. At one end of each strand there is aphosphategroup attached to the carbon atom number 5 of ...
In Escherichia coli, formamidopyrimidine-DNA glycosylase (Fpg, EC 3.2.2.23) removes 8-oxoG, Me-FaPy, and several structurally related lesions from damaged DNA (7, 8). Fpg is a component of the “GO system” that includes MutY, a mismatch adenine-DNA glycosylase, and MutT, an 8-oxod...
FORMATION AND BIOLOGICAL ROLE OF PYRIMIDINE ADDUCTS IN DNA Abstract鈥 Pyrimidine (Pyr) adducts constitute a significant fraction of the photoproducts formed in DNA exposed to far UV light. The primary and secondary DNA structure affects the rate of Pyr adduct formation; for example, it increases....
of RNA editing [49]. RNA editing is more likely to occur when the edited adenosine is preceded by a pyrimidine and followed by a G (e.g., 5’-UAG-3’) [17,50]. In addition to adjacent nucleotides, mismatches at processing sites can also increase the processing efficiency. Classical A...
