1·Results: There was no 24-base pair duplication in exon 10 in our cloned gene.

结果：所克隆的壳三糖酶基因在外显子10处没有2 4个碱基的重复序列。

2·The base pair ratio, at: GC, is constant within a species but differs between species.

GC之间的碱基比具有种内特异性，但在不同种之间往往是不同的。

3·By flipping this field's polarity the DNA strand can be ratcheted along, one base pair at a time.

通过转动电场的极性，DNA链会渐进式地前进，一次一对碱基对。

4·Instead a single strand of DNA can be read, one base pair at a time, and without the need for labelling.

仅仅一条DNA链就可以被识读出来，一次一个碱基对，不需要带上标识。

5·Researchers have also advocated assessing health risks within ethnic groups based on inherited variations in just one DNA base pair.

研究人员也主张，仅仅根据一个DNA碱基对的遗传变异，就可以评估不同种族的健康风险。

6·The core consists of 140 base pair of DNA wrapped around a globular histone bead containing two each of histones H2A, H2B, H3 and H4.

核小体核心由140个碱基对的DNA围绕一个组蛋白小球组成，每一个组蛋白小球包含两个H_2A、H_2B、H3和H4的四聚体分子。

7·So, in the case of neuroepithelial neoplasia, he said, they are looking for mutations outside of the 12 base pair segment of the gene.

因此，就神经上皮肿瘤而言，他们正在寻找此基因的12 bp片段以外的突变。

8·In Ames assay the strains were TA98 and TA100, which were able to determine base pair substitutions and frameshift mutation respectively.

所用的菌种为TA98和TA10 0 ，主要考察碱基对置换突变和移码致突变。

9·Much more information should emerge as Dr Paabo increases his one-fold coverage to 20-fold, the point at which almost every base pair is represented.

当柏保博士将他的拷贝数从1倍增加到20倍时，将会有大量的信息浮现出来，关键在于每一个碱基对都有代表性。

10·The cost of sequencing DNA has fallen from about $1 per base pair in the mid-1990s to a tenth of a cent today, and the cost of synthesising the molecule has also fallen.

DNA序列重排的成本在90年代中期是每个碱基对一美元，而现在的价钱是当时的十分之一，而且人工合成分子的成本也大大降低。
