查询词典 heterochromatic

Fluorescence in situ hybridization and immunofluorescence assay revealed that the DNA sequences associated with the heterochromatic knobs are highly divergent and heavily methylated compared with the sequences in the corresponding X chromosomal domains.

而通过NDA的分子原位杂交，专家在番木瓜的雄性区域发现了该区域有4个特异的异染色质疖，免疫荧光分析则揭示出这个区域与X染色体的相应区域发生了较大的分化，具有高度的甲基化。

The origin of the heterochromatic regions on the long arm of maize B chromosome was studied in two ways: the Southern signals of the CL-repeat; and its deletion, insertion, and mutation variants.

本研究分别以CL-repeat的南方杂合讯号以及因缺失、插入和突变造成的序列变异两个角度，来探讨玉米B染色体长臂远端异染色质(distal heterochromatin， DH)区的起源。

Using tertiary trisomes and hypoploids of a set of B-10L translocations, the CL-repeat signals and the variants in each of the three distal heterochromatic regions were identified.

利用一系列的B-10L易位染色体所产生的三级三染体和亚倍体，可以判断CL-repeat讯号及其变异产物在三个远端异染色质区(DH1， DH2， DH3)上的分布位置。

Chromosomes are also called supernumerary chromosomes, accessorychromosomes or extra chromosomes. They are supernumerary to the standardchromosomes set, which are found in thousands of plants and animals.They are often morphologically distinct from A chromosomes, being smaller and morehighly heterochromatic in most cases.

染色体又称超数染色体、附加染色体或额外染色体，是生物界中广泛存在的、独立于物种染色体组中常规染色体之外的一种特殊染色体。

"Think about a chromosome as being a highway," says Aramayo. In order to function properly, some sections of the highway must have illumination, which means DNA must be expressed, whereas other sections must not have illumination, which means DNA must not be expressed, or that the region must be heterochromatic.

Aramayo说，我们可以将染色体想象成一条高速路，为了正常运行，高速路的一些区段需要照明，也就是说DNA必须被表达；而其它区段则不需要照明，即DNA不需要表达，或这些区段必须被异染色质化。。。。。。。

First, miRNAs derive from genomic loci distinct from other recognized genes, whereas siRNAs often derive from mRNAs, transposons, viruses, or heterochromatic DNA.

第一，微小RNA 起源于明显不同于其他识别基因的基因位点，而小型干扰RNA通常起源于信使RNA、转座子、病毒或异染色质的 DNA。

The origin of the heterochromatic regions on the long arm of maize B chromosome was studied in two ways: the Southern signals of the CL-repeat; and its deletion, insertion, and mutation variants.

中文摘要本研究分别以CL-repeat的南方杂合讯号以及因缺失、插入和突变造成的序列变异两个角度，来探讨玉米B染色体长臂远端异染色质(distal heterochromatin， DH)区的起源。

The values of LEC is calculated by using some data regarding V~*_(λ from direct heterochromatic brightness comparison method in different luminance levels from 10~(-5 to 10~(2) cd·m~(-2); 10 degree visual angle.

LEC值可为道路照明设计时选择适宜的光源提供有益的参考。

Silenced chromatin, largely heterochromatic,contains a number of restrictive histone modifications, such as meH3K9, meH3K27, meH4K20,and histone deacetylation, which allow for a higher-order packing and inaccessibility to transcription factors.

沉默的染色质，大部分的是异染色质，包含大量的限制性的组蛋白修饰因子，例如meH3K9， meH3K27， meH4K20和组蛋白的脱乙酰作用，这些因子需要高度包装和不易转录因子。

These sequences possessed highly copy number in the genome and were named as RMX1-6 individually. When these sequences were hybridized to chromosomes of spiny eel, RMX6 was proved to be sex chromosome specific and it only located in heterochromatic regions.

在随机挑取的三百多个克隆中，分离得到了6个高度重复序列，它们在基因组中存在较高拷贝数，按照发现顺序分别命名为RMX1—6(Repetitive sequence inMicrodissected X chromosome)。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
