1. If you were to mix the bases of dNa with water, would you expect them to form co-planar hydrogen bonds, or stack on top of each other. What about in an organ ic solvent such as DMso (Hint, the answer is different in each case). Justify your answer

最近连续阅读了”青年话题″版上有关水价格问题的几篇″不同观点\,对于 提髙水价,限量用水\的政策措施,大家有各种各样的意见。有人认为,水涨 价,有利于减少浪费,提高大家的节水积极性;也有人认为,水资源的需求缺 乏弹性,即使涨价也没有什么用;更有人认为,水资源涨价,是劫贫济富,不 公平。作为制度分析学者,我是如何看待这一问题呢? 首先要看提髙水价这一特定的政策选择可能导致什么样的直接效率效应
