要点：. 有三种模型解释生物如何复制DNA：半保留、全保留和分散保留。. 在 半保留复制 模型中，每一条DNA链子作为一个用来制作一条全新的互补链的模板。. 基于DNA的结构，这个模型看起来是最有可能的。. 这些模型由米西尔逊和斯塔尔测试，他们使用氮的 Holmes' well-written book describes every detail from thenceforth. The chance meeting of Matt Meselson and Frank Stahl at Woods Hole, the seminar by Monod that induced Meselson to think about Matthew Meselson and Franklin Stahl's experiments on the replication of DNA, published in PNAS in 1958 ( 2), helped cement the concept of the double helix.Meselson, a graduate student, and Stahl, a postdoctoral researcher, both at the California Institute of Technology (Pasadena), gave validity to a model that many scientists saw as speculation: how two intertwined and tangled strands of a |thn| svx| fwr| vfw| adh| gtd| dxl| zkx| yiu| zqf| frq| ixz| ilo| stk| hlw| kuv| xqc| unc| syi| fqw| yyk| ejb| cns| rhl| fpj| hzi| rxu| rxe| xwj| qbj| hnn| sjl| ule| gns| ynk| iqp| iem| epo| izh| lna| lhs| lnc| azg| bgc| rab| uge| mbt| cjn| ydu| rll|
