cnofiguration と conformation の違いにお悩みですか？ configuration=立体配置、conformation=立体配座 と訳します。 前者は結合軸の回りの回転等でも変わらない分子の空間構造。 後者は結合軸の回りの回転等で変わる分子の空間構造。 これを念頭に置くと、訳は 「砂糖とその周辺の原子の立体配置はFurbergの標準立体配置に近く、 砂糖は結合した塩基におおよそ垂直である。」 言い換えると 「砂糖（分子）とその周辺の原子の立体配置はFurbergの標準立体配置に 近く、砂糖（分子鎖）は（それに）結合した塩基にほぼ垂直である。」 この文だけではsugerが砂糖か糖かは判断できません。 塩基の付いた砂糖は、苦い砂糖？？ それとも塩基の付いた糖類？？ ついでに There is a residue on each chain every 3・4 A.in the z-direc-tion. の訳は 「各（分子）鎖のｚ方向の３，４?毎に残基が有る（付いている）。」 と思います。 しかし、３，４?（オングストローム）は小さすぎるような気もします？

糖とその近くの原子の配置は、フルベルグの「標準配置」に近い、即ち糖は結合された基に対して大体直角になっている。

下記の論文を訳してください。 1)We wish to put forward a radically different structure for the salt of deoxyribose nucleic acid.This structure has two helical chains cach colied round the same axis(see diagram).We have made the usual chemical assumptions,namely,that each chain consists of phophates di-ester groups joining B-D-deoxy-ribofuranose residues with 3',5' linkages.The two chains (but not their bases) are related by a dyad perpendicular to the fibreaxis.Both chains follow right-handed helices,but owing to the dyad the sequences of the atoms in the two chains run in opposite directions.Each chains loosely resembles Fur-berg's model No.1 ; that is,the bases are on the inside of the helix and the phophates on the outside.The configuration of the sugar and the atoms near it is close to Furberg's 'standard configuration',the sugar being roughly perpendicular to the attached base.

下記の英文を和訳してください 1)In other words,if an adenine forms one member of a pair,on either chain,then on these assumptions the member must be thymine;similarly for guanine and cytosine.The sequences of bases on a single chain dose not appear to be restricted in any way.However,if only specific pairs of bases can be formed,it follows that if the sequence on the other chain is autmatically determined. 2)It has been found experimentally that the ratio of the amounts of adenine to thymine,and the ratio of guanine to cytosine,are always very close to unity for deoxyribose nucleic acid. 3)It is probably impossible to build this structure with a ribose sugar in plase of the deoxyribose,as the extra oxygen atom would make too close a vander Waals contact.

下記の英文を訳してください 1)There is a residue on each chain every 3・4 A.in the z-direc-tion.We have assumed an angle of 36゜ between structure repeats after 10 residues on each chain,that is,after 34 A. The distance of a phophates atom from the fibre axis is 10 A. As the phophates are on the outside,cations have easy access to them. 2)The structure is an open nne,and its water contents we would expect the bases to tilt so that the structure could become more compact. 3)The novel feature of the structure is the manner in which the two chains are held together by the purine and pyrimidine bases.The planes of the bases are perpendicular to the fibre axis.They are joined together in pairs,a single base from one chain being hydrogen-bonded to a single bases from the other chain,so that the two lie side by side with identical z-co-ordinates.One of the pair must be a purine and the other a pyrimidine for bonding to occur.

Molecular Structure Of Nucleic Acids A Structure for Deoxyribose Nucleic Acid We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.). This structure has novel features which are of considerable biological interest. A structure for nucleic acid has already been proposed by Pauling and Corey (1). They kindly made their manuscript available to us in advance of publication. Their model consists of three intertwined chains, with the phosphates near the fibre axis, and the bases on the outside. In our opinion, this structure is unsatisfactory for two reasons: 1) We believe that the material which gives the X-ray diagrams is the salt, not the free acid. Without the acidic hydrogen atoms it is not clear what forces would hold the structure together, especially as the negatively charged phosphates near the axis will repel each other. 2) Some of the van der Waals distances appear to be too small. Another three-chain structure has also been suggested by Fraser (in the press). In his model the phosphates are on the outside and the bases on the inside, linked together by hydrogen bonds. This structure as described is rather ill-defined, and for this reason we shall not comment on it. We wish to put forward a radically different structure for the salt of deoxyribose nucleic acid. This structure has two helical chains each coiled round the same axis (see diagram). We have made the usual chemical assumptions, namely, that each chain consists of phosphate diester groups joining ß-D-deoxyribofuranose residues with 3',5' linkages. The two chains (but not their bases) are related by a dyad perpendicular to the fibre axis. Both chains follow right-handed helices, but owing to the dyad the sequences of the atoms in the two chains run in opposite directions. Each chain loosely resembles Furberg’s (2) model No. 1; that is, the bases are on the inside of the helix and the phosphates on the outside. The configuration of the sugar and the atoms near it is close to Furberg’s ‘standard configuration’, the sugar being roughly perpendicular to the attached base. There is a residue on each chain every 3.4 A. in the z-direction. We have assumed an angle of 36° between adjacent residues in the same chain, so that the structure repeats after 10 residues on each chain, that is, after 34 A. The distance of a phosphorus atom from the fibre axis is 10 A. As the phosphates are on the outside, cations have easy access to them. This figure is purely diagrammatic. The two ribbons symbolize the two phosphate-sugar chains, and the horizontal rods the pairs of bases holding the chains together. The vertical line marks the fibre axis.

The principal factor that determines whether a nucleus is stable is the neutron-to-proton ratio. For stable atoms of elements having low atomic number, the n/p value is close to 1. As the atomic number increases, the neutron-to-proton ratios of the stable nuclei become greater than 1. This deviation at higher atomic numbers arises because a larger number of neutrons is needed to counteract the strong repulsion among the protons and stabilize the nucleus. この英文を和訳してください。核化学に関する英文です。
