染色体

Genetic instability has been described in all Streptomyces species studied so far, in which linear chromosome is deleted at both ends and often circularized by recombination.

链霉菌中DNA不稳定性普遍存於各亚种间，一般会造成线形染色体的末端序列删除并经由重组而产生环形的染色体。

The second part introduced two main algorithms of chromosome recognition: chromosome detaching algorithm and skeleton thinning algorithm.

第二部分介绍了染色体识别的两个主要算法：染色体分离算法和骨架细化算法。

Those showed that the E chromosome of thinopyrum intermedium inserted the genome of common wheat, and it disarranged the original matching of chromosome.

这些现象表明中间偃麦草的E组染色体进入了普通小麦的基因组，影响ABD组染色体配对。

This approach is valuable for genes whose existence is implied by genetics, but whose nature is unknown. One example is the gene zfy located on the human Y chromosome. Figure 2.17 shows a zoo blot using a probe from this region. It hybridizes specifically with sex chromosomes of mammals and also with

这个方法对于那些通过遗传学已证明存在的，但其性质还未知的基因是很有效的，例如人Y染色体上的zfy基因，它可以和哺乳动物或其它一些物种的性染色体杂交，且包含一个可译框，于是证明它是一个保守基因。

He used 37 markers on chromosome, which was chosen because it has already been implicated in reading disabilities.

他使用了一个染色体上的37个标记，选择该染色体是因为它与阅读能力的丧失有关联。

The seeds of Adzuki bean were irradiated by 60 Co γ ray of 0～700Gy.The results showed that:(1)The sub\|lethal dose(LD 50 )was 389Gy and the early seedling leaf at M\-1 showed incised,chlorotic,yellow,mosaicand curly edge.The absorbed dose was related with the rate of misshaped leaf.Chromosomal aberration, chromosome bridge and fragment of M\-1 in the tip were observed.If the seed was irradiated with 400Gy,the rate of abnormal cell at the root was more than 10%.The relationship between pollen fertility and irradiation dose was negative correlated.

本试验研究结果表明：60 Coγ射线辐照小豆种子的半致死剂量平均为 3 89Gy ，且M1生长初期叶片性状有明显的叶面缺刻、叶色缺绿、叶形不对称、叶缘卷曲、花叶、黄叶等致变现象，各种畸型叶出现频率与辐照剂量大小有关；M1根尖细胞中有多种染色体畸变类型，以染色体桥和断片频率较高，辐照剂量在 40 0Gy以上时根尖细胞异常率达 1 0 %以上；植株花粉育性与辐照剂量呈极显著负相关，京农 2号植株花粉育性达 5 0 %时的辐照剂量为 3 78Gy。

Defect is actually a man woman, y chromosome is the chromosome of all 46 kinds of the most sick, most redundant, one of the most pays for doing nothing.

男人实际上就是缺损的女人，y染色体是所有46种染色体中最病态，最多余，最好吃懒做的一个。

SATB1 folds and remodels the chromatin -- the intertwined DNA and proteins that form chromosomes -- into new shapes, bringing even distant parts of the genome together for coordinated control of gene expression_r and regulation.

SATB1打开并重新改型这些染色体——使DNA和蛋白质缠绕而形成同源染色体——变成新的形状，使位置较远的基因组结合从而协调基因的表达和调控。

With this method a very good effect of chromosome squashing could be obtained.

卷丹染色体数目观察表明，3个卷丹居群的染色体数目均为2n=3x=36。

The method of long time culture and chromosome preparation of villi is simple, stable and reliable.

绒毛细胞长期培养法和染色体制备方法简单、技术稳定、结果可靠，可用于胎儿染色体疾病的产前诊断。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
