If two mitochondrial DNA sequences differ by a single unit, current guidelines require the analyst to report the comparison as inconclusive.

如果两个线粒体dna的序列差异达到一个单位，目前的指导手册要求分析人员把它当作无效的比较。

Scientists revealed that up to 4% of our DNA is Neanderthal after the first comparison of the complete genomes of humans and our much maligned Cousins.

在第一次全面比较了人类和尼安德特人的基因组以后，科学家们发现，人类有4%的DNA来自于这些遭到恣意诽谤的远亲们。

Computer comparison then shows which human genes correspond in DNA sequence and thus, presumably, in function, to the genes in these "model" organisms.

通过对比找出人类基因中相同序列，就可以推测和相应的生物模型中的基因有类似的功能。

Then, using DNA-comparison techniques, the scientists were able to determine that Denisovans were distinct from both modern humans and Neanderthals, yet closely related to the latter.

然后，通过DNA比对技术，科学家们就能够确认丹尼索万人与现代人，尼安德特人之间的区别，然而结果是亲密的接近后者。

Through comparison among 5 different methods of DNA template extraction, heat-lyse treatment was selected for its easy-operation, low-cost and celerity.

通过对5种不同的DNA模板提取方法的比较，选定了操作简便、快速、费用低廉的热裂解法。

Results show that high-LET heavy ion radiation more effectively induces DNA DSBs in comparison with low-LET radiation, and produces DSBs that are distributed more locally and more densely.

结果表明，具有高let的重离子辐射与低let辐射相比，能够更有效的诱发DNA分子发生双链断裂，并使双链断裂的分布更局部和更密集。

Comparison of two DNA sequences suggested that both gene mutation and genetic recombination were involved in the divergent evolution process.

序列排比结果说明在淀粉酶基因的趋异进化过程中，基因突变和遗传重组都曾起过作用。

Recurrent mutations were found in 10 genes and the somatic nature of these mutations was analyzed by comparison with generic DNA from buccal swabs.

在10个基因中发现频发突变，通过与口腔拭子中的基因组d NA比较分析这些突变的体细胞特征。

Subtractive hybridization is an approach allowing comparison of two DNA populations and isolation of fraction enriched in differentially distributed molecules.

消减杂交手艺是一种方法，许可两种DNA地生齿和孤立局部富集差别散布地分子。
