1 下列关于WatsonandCrick的DNA双螺旋模型的说法,正确的是()。A. 组成双螺旋的两条DNA链反向平行B. 碱基对位于双螺旋的内侧C. 维系双螺旋结构的作用力主要是碱基堆积力D. DNA双链是左手螺旋 2 下列关于Watson and Crick的DNA双螺旋模型的说法,正确的是( )。 A、组成双螺旋的两条DNA链反向平行 B、碱基对位...
watson and crick之前碱基配对规则 沃森和克里克在提出碱基配对原则时,认为腺嘌呤(A)必须与胸腺嘧啶(T)配对,鸟嘌呤(G)必须与胞嘧啶(C)配对,这是双链DNA分子中碱基配对的规律。因此,沃森和克里克之前的碱基配对规则就是A与T配对,G与C配对。这一规则的发现对于生物学领域具有重要意义,为DNA双螺旋结构的提出奠定了...

因此,Watson、Crick和Wilkins共享了1962年诺贝尔生物医学奖。此后,享有“DNA之父”美誉的Watson便成为了学术界泰斗般的存在。 虽说诺奖一向是科研者梦寐以求的荣誉,但这不代表每个诺奖光环加身的科学家能过好后半生。Watson就是一个例子。 谁能想到,在这个特别强调严谨和理性的科研界,这位宗师级的人物会屡次口无遮拦...

In 1953. Watson and Crick, two scientists at Cambridge University, England. discovered the structure of the acid DNA.In 1973, biochemists Cohen and Boyer cut out a sequence of genes. A clone is an organism which is I ( genetic ) identical to another one. But it's now certain that no...

可能正如一位网友留言说的:做科学,首先要有人文素养,否则一切都是白费。无论处于什么地位,都不应该忘记最基本的原则,尊重他人,谨言慎行。 参考资料: http://www.bbc.co.uk/history/historic_figures/crick_and_watson.shtml 撰文丨萌董董 排版丨萌董董
