时间Tue Jan 26 10:11:08 2010
※ 引述《demon123 (结束後开始)》之铭言：
: in comparison with DNA-DNA double helices, the stability of DNA-RNA and
: RNA-RNA helices is:
: A. RNA-RNA > DNA-RNA > DNA-DNA
: B. DNA-DNA > DNA-RNA > RNA-RNA
: C. DNA-RNA > RNA-RNA > DNA-DNA
: D. RNA-RNA > DNA-DNA > DNA-RNA
: E. DNA-DNA > RNA-RNA > DNA-RNA
: 答案是给A 可是我不知道为什麽RNA-RNA会大於DNA-DNA
: DNA-DNA不是应该比较稳定吗?
: 谢谢各位!
1.Lehninger 4th edition p.292(d.s DNA & RNA can be denatured那段)
(5th edition p.288)
最後一段话"The phisical basis for their differences in thermal
stability is not known".
嗯:P
2.这个题目少给一个条件：pH=7 XD
