半保留的

One could denature the DNA, and then subject the single-stranded sample to CsCl centrifugation.

CsCl梯度离心的结果虽然排除了全保留复制的可能性，但不能根据这一结果就可证明DNA的复制是半保留复制，因为弥散复制也会出现同样的结果。

This could be done in practice by using an alkaline CsCl gradient, as the two DNA strands will denature at high pH.

用同样的样品和相同的技术手段即CsCl梯度离心将半保留复制和弥散复制区分开来的方法是将DNA样品变性，然后利用碱性CsCl梯度离心技术对单链DNA进行离心，半保留复制会出现两条带，而若是弥散复制则出现一条带，如下图所示

This process is comes through the named half retention duplication mechanism to be able to complete smoothly.

这个过程是通过名为半保留复制的机制来得以顺利完成的。

The aphidicolin-sensitive DNA synthesis resulted from semiconservative DNA replication as confirmed by neutral 〓 equilibrium gradient centrifugation.

用中性〓平衡梯度离心证实了aphidicolin敏感的DNA合成是半保留式的。

Tourists will benefit from a new ticketing system allowing them to prepay for reserved half-hour time slots online.

游客将受益于新的票务系统允许他们以预付保留半小时的时间上网。

Appears to you that this evidence that DNA replicates in the semiconservative manner, but you are wrong.

根据这一结果，你认为DNA是以半保留方式进行复制，但你的观点是不正确的，为什么？

An attractive hypothesis has been a semiconservative mechanism in which parental histones are combined with newly synthesized histones within the same core nucleosome.

一个有吸引力的假说是半保留的机制，在这一机制中，亲本的组蛋白和新合成的组蛋白共存于同一核小体核心中。

Why What other experiment could you perform (using the same sample and technique of CsCl centrifugation) that would further distinguish between semiconservative and dispersive modes of replication

请你设计另一个实验方案（用同样的样品和相同的技术手段即CsCl梯度离心）能够有效地将半保留复制和弥散复制这两种复制方式区分开来。

Semiconservative replication :The two strands of DNA double helix are separated, each strand serves as a template for the synthesis of a new complementary strand, producing two daughter molecules. Each daughter molecule has one parental strand and one newly synthesized strand.

半保留复制： DNA 生物合成时，母链 DNA 解开为两股单链，每股单链分别作为模板，以 dNTP(dATP 、 dGTP 、 dCTP 、 dTTP)为原料，按照碱基配对(A － T 、 G － C)规律与模板上的碱基配对，经依赖 DNA 的 DNA 聚合酶催化，合成一条与模板互补的新链，新形成的两个子代 DNA 与亲代 DNA 碱基序列一致，子代 DNA 分子中一股单链是从亲代完整地接受过来，另一股单链是新合成的，故称为半保留复制。

In this portrait, Chagall is more interested in depicting the Poet's destiny than his individual personality.

不过，他仍保留了诗人的特征─圆头、深陷的双眼─一个古怪地简化了的头部，藏在半人半兽的面具背后，充份表达了诗人内心世界的一面。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。

Uncovering their weak spots, so I can defeat them.

揭露出他们的弱点，这样我就可以打败他们了。
