It is primed one time during synthesis and uses the DNA strand 3’ to 5’ as template. 前导链是指随着亲本双螺旋的解开而按照5′ 3′方向连续合成的DNA子链,以3′5′方向的亲本链为模板。 Lagging stand uses the DNA strand that runs 5’ to 3’as template and synthesis DNA non-...
Leading Strand与Lagging Strand的区别 在DNA复制过程中,前导链和后随链(Lagging strand)是同时合成的,但它们的合成方式和特点有所不同。前导链的合成是连续的,只需在复制起点上有一个引物,一旦形成复制叉后,DNA聚合酶就可沿着亲链模板不断地加上新的核苷酸,从而合成一条新的连续的子...
在DNA复制时,以3′→5′方向为模板合成的一条新链是连续的,称前导链(leading strand),它的延伸方向与复制叉的移动方向相同 另一条新链的合成是不连续的,由许多5′→3′方向的冈崎片段组成,这条新链称后随链(lagging strand),它的延伸方向与复制叉的移动方向相反。后随链的引发过程往往由引发体(primosome)来...
This possibility of differential replication fidelity arises from the distinct modes of replication in the two strands, one strand (the leading strand) being synthesized continuously, the other (the lagging strand) discontinuously in the form of short Okazaki fragments. We have constructed a series ...

What is the basis for the difference in how the leading and lagging strands of DNA molecules are synthesized? a. The origins of replication occur only at the 5′ end. b. Helicases and single-strand binding proteins work at the 5′ end. c. DNA polymerase can join new nucleotides only to...
