- That assumption was based on studying mitochondrial lineage - a small part of the genome , or dna , that is passed exclusively from mothers to offspring .
- 这一假设基于线粒体世系研究也就是基因或是脱氧核糖核酸的一小部分物质，同时仅仅由母亲传给子嗣。
- Many of the key molecules for life have a specific direction , or handedness : dna twists to the right , amino acids to the left .
- 构成生命体的许多关键分子都有一个特定的导向，或者说是旋向性：脱氧核糖核酸右旋，氨基酸左旋。
- A gene is a strand of dna that holds the code for the amino acids that make proteins . And proteins do the work of the body .
- 基因是指链状的脱氧核糖核酸，其中包含着指导合成氨基酸的密码子，而氨基酸则构成了蛋白质，蛋白质又组成了生物的躯体。
- Scientists at the university of aberdeen say a genetic switch - dna which turns genes on or off within cells - regulates appetite and thirst .
- 英国阿伯丁大学的科学家们指出基因开关-即控制细胞内基因的脱氧核糖核酸（dna）-能调节人的饥渴。
- But after studying dna from inside the cell nucleus , using samples from 19 polar and 18 brown bears , frank hailer of germany 's biodiversity and climate research centre and colleagues reached a very different conclusion .
- 但是通过利用19只北极熊和18只棕熊个体样本，研究细胞核内的脱氧核糖核酸后，德国生物多样性和气候研究中心的佛兰克海勒得出了一个完全不同的结论。
- In research presented sunday at the international conference on alzheimer 's disease in vienna , dr. roses and his team looked at the area of dna surrounding the apoe gene .
- 周日在维也纳举行的国际老年痴呆症大会上，罗西斯及其研究小组进行了演示，他们研究了apoe基因周围的脱氧核糖核酸（dna）部分。
- These are a normal by-product of mitochondrial activity , but are usually mopped up by special enzymes before they can escape and cause harm-for instance , by damaging a cell 's dna .
- 这是线粒体活动中的副产品，但在他们游离变得有害之前，比如，破坏细胞的脱氧核糖核酸（dna），会由特殊的酶清除干净。
- Since there have been adverse results using viruses as agents to transfer genes into humans , the researchers instead chose to transfer the hmaxi-k gene using " naked dna , " or dna stripped of any proteins .
- 由于利用病毒制剂将基因转移到人体总会产生不良效果，科学家们改用裸dna（脱蛋白的脱氧核糖核酸）来转移hmaxi-k基因。
- Instead , all the dna present in a sample is sequenced at the same time ; then clever computer software works out the contribution of different microbes to the genetic soup .
- 相反，存在于一个样本中的所有脱氧核糖核酸（dna）都被同时测序，然后由更智能的计算机软件分析出各种微生物对这碗“基因汤”的贡献。
- Other , more established oncologists point out that cui 's mice are genetically uniform ; humans , with their distinct dna differences , would run a deadly risk of the donated cells attacking their host , even if they aren 't rejected first .
- 其他较有地位的肿瘤专家指出，崔政的老鼠在基因上是一致的，而人类的脱氧核糖核酸是明显不同的，即使起初注入细胞并不受到排斥，但它们对主体细胞的攻击会造成致命的危险。
