(1)Leading strand is the DNA strand that synthesized continuously in the 5′ to 3′ direction as the parental duplex is unwound. 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...

True or False: A pyrimidine in one strand of DNA always base pairs with a purine in the opposite strand. Explain. More primers are used in lagging strand synthesis than in leading strand synthesis. True False True or false? The two DNA strands are anti-...
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 ...

Gene 4 protein and DNA polymerase catalyze processive leading strand synthesis. 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 ...
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...
