异基因

Now a way has been found to make greener tyres by using genetically modified bugs to produce isoprene biologically.

今天我们发现了一种制造更"绿色"轮胎的方法，即通过利用基因改良的细菌来生物合成异戊二烯。

Classification examination was put into practice for only normal cells observed.For the dubious specimen,tuberculosis-Ab,acid-fast bacteria staining,flow cytometry,CD series,gene,DNA aneuploidy,ZPP and tumor markers etc were detected. Results Tuberculosis lymph gland inflammation coverd highest rate:546 cases (36%) in tuberculosis node was 252 cases (46.2%),lymphonode period was 184 cases (33.7%),early tuberculosis lymphagland inflammation was 233 cases (44.7%).

利用改良一次性5～10ml注射器(22G、7号注射器，外径＜0.7mm)，针吸取材、涂片、行改良瑞-姬双染技术，低倍镜查找特殊异常细胞，油镜仔细观察细胞形态结构特征，对于未见异常细胞要进行分类检查，对疑难标本，同时做结核抗体、抗酸菌染色、流式细胞仪、CD系列、基因、DNA异倍体、锌原卟啉、肿瘤标志物等检测指标。

Dobzhansky (1970) Races are genetically distinct Mendelian populations.

种族是基因上相异的孟德尔遗传群体。

Thus most individuals in an outbreeding population could be called hybrids, and geneticists apply the term to the F1generation resulting from a monohybrid cross, where the offspring differ in the alleles of a single gene.

大多数异系交配的个体可以被称为杂种，遗传学上常将进行单因子杂交得到的 F1代称为杂种，它们在一个位点上具有不同的等位基因。

An Edinburgh University study of identical and non-identical twins suggests genes may control half the personality traits keeping us happy.

爱丁堡大学针对同卵与异卵双胞胎的研究显示，基因可能控制一半让我们快乐的个性特徵。

They are often morphologically distinct from A chromosomes, being smallerand more highly heterochromatic in most cases. B chromosomes do not pair with Achromosomes, and they are inherited in a non-Mendelian way, exhibiting meiotic andmitotic instability and nondisjunction. However, B chromosome DNA is quiteidentical to the corresponding sequence on the A chromosome complement. So far afew B chromosome specific DNA sequence have been identified. Specific DNAsequences on B chromosome have been the attractive research area on Bchromosomes.

现已在千余种植物和近三百种动物中被发现。B染色体与物种中正常染色体不同：独立于整倍体基因组之外，减数分裂时不与A染色体发生联会和配对，细胞分裂后期不分离，非孟德尔遗传，富含异染色质，不含对宿主主要性状有影响的基因等。B染色体DNA的分子组成既与A染色体极为相似，具有A染色体DNA分子组成的一般特征：富含重复序列和转座成分，染色体三大功能组件DNA高度同源；又与之相区别，含有B染色体特异的DNA序列，这些DNA序列可以为探讨B染色体的起源和进化提供有价值的信息。

Because of heavy heterozygosity of cassava genome caused by stack propagation and outcross in longtime, the practice of biotechnology would resolve these problems in broad background.

由于木薯是无性繁殖的异花授粉作物，传统育种方法在基因重组方面受到局限；生物技术的应用却能够在很大程度上解决上述问题。

High outcrossing rate might lead to high gene flow frequency and the maximum frequency of gene flow was determined by outcrossing rate.

实验结果显示，强烈的自花授粉竞争可能是导致栽培稻品种间极低的异交率以及基因漂移频率的主要原因之一。

Eui gene of rice was an important genetic factor to improve outcrossing traits of hybridrice.

水稻长穗颈基因eui是根本上改良杂交稻异交性状的重要遗传因素。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
