We obtained a strain that increased the level of functional expression of heterologous protein with multiple bonds.

本研究建立了在大肠杆菌染色体上进行基因敲入的方法，观察了共表达及敲入到染色体上的折叠调节因子对外源蛋白功能性表达的影响，获得了对外源蛋白的功能性表达有促进作用的菌株。

A gamete containing a diploid number of chromosomes, rather than the usual haploid number.

2一个包含二倍体数目染色体而不是通常单倍体数目染色体的配子。

Human β E globin gene can be detected in different position of different chromosomes in tr...

FISH能直观地反映外源基因在转基因动物染色体上的整合状态，该方法可对转基因动物及基因转移研究中的外源基因整合后进行染色体定位检测。

Using the methods of classical shape size measuring and chromosome analysis, we studied the morphological characters and Karyotype of Cobitis sinensis in Xiangjiang River. We also investigated the evolution line and Karyotype polymorphism of the C . sinensis by the methods of cytological classification and cytocatalytic. Our results suggest that the formation of chromosome polymorphism was concerned with heterologous hybridization and some of C . sinensis may perpetuate in a clonal manner by natural gynogenesis.

本文以湘江流域的中华花鳅为研究对象，运用经典的形态测量观察方法、染色体制片技术对中华花鳅的形态生态特征、染色体组型进行了初步研究：运用细胞分类和进化方法对中华花鳅的核型演化和核型多态现象的形成进行了分析，提出：其核型多态的形成牵涉到鳅科鱼类的异源杂交，某些中华花鳅可能是行雌核发育生殖的。

An organism or cell having two sets of chromosomes or twice the haploid number.

有两套染色体或者是单倍体两倍的数目染色体的细胞或有机体。

In this experiment we find haploid of bear has 96 bars masculine bands It showed different bands.

本实验发现黑熊的单倍体有96条阳性带纹，且黑熊每对染色体都有其独特的带纹特征，其带纹的数目和精细程度随着染色体长度的增加而增加。

Objective: To analysis the aberration of chromosome 9 heterochromatin for persons suspected to have chromosome abnormalities.

文章摘要：目的分析疑有染色体异常个体的9号染色体异染色质区的变异。

The C-banded heterochromatin of satellites of Ae.tauschii can be used as a marker in genetic research and genetic research and genetic manipulation.

但是不同节节麦居群间5D染色体上的这个随体C带存在多态性。5D染色体上的随体区域可以作为小麦遗传分析和遗传操作的标记性状。

Chromosomal analysis of skin cells from 8 tufted deer were studied by using primary culture and subculture.We found 4 different karyotypes in all and a new karyotype, different with the others studied before, was found. There were 47 chromosomes in somatic cell of the new karyotype, including a pair of heteromorphic X chromosomes, one was telocentric chromosome, the other was subtelocentric chromosome.

采用原代培养和传代培养方法对来自成都动物园的8头毛冠鹿的皮肤细胞进行了染色体研究，结果出现4种不同的核型，有一种核型与以前所报道的几种核型不一致，确定为新核型（2n=47♀，X染色体为异型，）。

Recombination suppression in the sex-determining region and accumulation of deleterious mutations lead to degeneration of the Y chromosomes in many species with heteromorphic X/Y chromosomes.

这个问题一直困扰着科学家，在2008年最后一期的世界著名杂志《基因组研究》上，王秀娥和张文立博士发表了《番木瓜原始Y染色体的雄性特异区中DNA甲基化和异染色质化》的研究论文，初步揭示了性染色体的起源变化机制。
