染色体

This result suggests that genes are not disjointed entities with parts spread out from one end of a chromosome to another.

这个结果表明，基因并非独立存在的，分散于染色体一端到另一端各个部分的个体。

The purpose of the research is: 1 to make the distinguishment of these hybrid rice combinations and their parents; 2 to establish a set of screening pictures and DNA fingerprint map concerning these super hybrid rice combinations and their parents; 3 to find a convenient method for identification of rice seed purity.In this study, 144 SSR primer pairs distributing in 12 rice chromosomes were used to detect the experimental materials.

本研究通过SSR分子标记技术分析进行超级杂交稻先锋和苗头组合的鉴定，获得以下结果：(1)对分布于水稻1-12号染色体的144对SSR引物进行了筛选，有47对能够在实验材料中显示较好的多态性通过，占检测引物的32.6％。

Homology search of genomic DNA can reveal pseudogene sequences, and some properties of pseudogenes such as population, distribution, and homology family can be examined.

通过序列同源性搜索，可以收集基因组中假基因的群体特性、染色体分布和同源家族等特性。

In this study,we have identified C2H2 ZFP genes in the silkworm,and acquired the basic information for these genes,such as gene distribution on chromosome,gene family information and expression information.This information will be useful for further functional studies on these genes.

综上所述，本研究对家蚕基因组中的C2H2型锌指蛋白基因进行了鉴定，并通过分析获得了这些基因的基本信息，即染色体分布、基因家族信息和基因表达信息等，这些信息为进一步对家蚕C2H2型锌指蛋白基因进行功能研究打下了基础。

According to the results this paper also analyzed genes distribution rule in chromosomes.

在此基础上探讨了这些基因在染色体上的分布趋势。

We focus the analysis on the distribution rule in pericentromeric region.

显示出编码序列跟内含子序列染色体的分布不同。

Barley seeds were irradiated with five different doses of 60 Co-γ ray.There were many kinds of chromosome aberration in pollen mother cells,such as bridge,laggards in anaphase I and anaphase II,asymmetrical division in anaphase I and asynchronous division in anaphase II,ring quadrivalent in metaphase I,three pole division and micro-nuclei in telophase I,micro-nuclei in tetrad and some micro-nucleus separates from the tetrad to form polyad.

大麦种子经5种不同剂量γ射线辐照后， M1植株的花粉母细胞出现多种染色体畸变类型，例如后Ⅰ、后Ⅱ中出现桥、落后，后Ⅰ中出现不对称分裂，后Ⅱ中出现不同步分裂，中期Ⅰ出现环状四价体，末期Ⅰ中有三极分裂和微核，四分体中出现微核且有的微核独立于四分体，从而形成多分体。

Curly is a easily distinguishable dominant mutant wing character.

卷翅是易以识别的果蝇翅膀的显性突变，是黑腹果蝇2号染色体上最常用的显性翅膀标记，但对Cy的分子特征却不清楚。

A total of 21 QTLs controlling the seed dormancy were detected in this study, distributed on the 12 chromosomes.

共检测到21个控制种子休眠性的QTL，分别分布在水稻的12条染色体上。
