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-...

Explain why DNA polymerase can continuously add fragments onto the leading strands 3'-5', but cannot do the same for the lagging strand. During transcription, on which strand will RNA polymerase be located? What is the role of DNA ligase in the elongation? What is the ...
1998. Unequal fidelity of leading strand and lagging strand DNA replication on the Escherichia coli chromosome. Proc. Natl. Acad. Sci. USA 95:10020-10025.Fijalkowska IJ, Jonczyk P, Tkaczyk MM, Bialoskorska M, Schaaper RM (1998) Unequal fidelity of leading strand and lagging strand DNA ...
One of the strands, known as leading strand, is continuously created throughout DNA replication. The other, known as the lagging strand, is produced in pieces. This results in two semi-conservative DNA molecules, each with one old and another strand....
题目 (翻译)The leading strand is synthesized continuously, while the lagging strand is synthesized in short stretches known as Okazakifragments. 相关知识点: 试题来源: 解析 正确答案:答:前导链是连续合成的,而后随链是以短的直线状的冈崎片段合成。 反馈 收藏 ...
coli is not the result of DNA repair processes. Furthermore, we show that the Okazaki fragments contain about equal amounts of leading- and lagging-strand sequences. These results are most consistent with the discontinuous DNA replication model as originally proposed by Okazaki et al. 展开 ...

aFurthermore, in the absence of WRN, leading- and lagging-strand DNA synthesis are uncoupled at replication forks, and POT1 is required for efficient replication of C-rich telomere strands 此外,在没有WRN时,铅和绝热材料子线脱氧核糖核酸综合被拆在复制叉子,并且POT1为富有C的telomere子线的高效率的...
Gene 4 protein molecules serving as helicase remain bound to the template as leading strand synthesis proceeds greater than 40 kilobases. Primer synthesis for lagging strand synthesis is catalyzed by additional gene 4 protein molecules that undergo multiple association/dissociation steps to catalyze ...
