染色质的

Fluorescence in situ hybridization technique is a most effective method of detecting alien chromatin at molecular level.

荧光原位杂交是在分子水平上检测外源染色质的一种有效方法。

Nucleosome is the basic unit of chromatin.

核小体是染色质的基本单位。

Granulosus is further;2. In differentiation of closely relatedspecies, the changes in heterochromatin and pericentric inversions are key factors, this is wellnoted in the small chromosomes;3. A. mantzorum has well-differentiated XY type sex chromo-'.omes, the Y chromosome is mainly composed of euchromatin, but has strong C-band in themiddle of the long arm. It is suggested that the Y chromosome of A. mantzorum is in the-initial stage of sex chromosome differentiation.

结果表明：(1)四川湍蛙、理县湍蛙和棕点湍蛙之间的亲缘关系较近，而它们与棘皮湍蛙的亲缘关系较远；2）在近缘种的分化中，染色体结构异染色质的变化和臂间倒位是重要的因素之一，这在小型染色体上表现得尤为突出；四川湍蛙具有在形态上分化很明显的性染色体。C带分析表明，此性染色体主要由常染色质构成，但在其Y染色体的长臂上存在明显的中间C带，推测尚处于性染色体分化的初期阶段。

In many eukaryotes, including plants, DNA methylation provides a heritable mark that guides formation of transcriptionally silent heterochromatin.

在很多真核生物中，包括植物，DNA甲基化提供了一个可遗传的标记，该标记可以引导转录沉默异染色质的形成。

Our data suggest that these histone modifications may act cooperatively to prepare chromatin for transcriptional activation.

我们的数据表明，这些组蛋白修饰可能共同作用于染色质的转录激活。

There were more Ca〓 deposite granules in and around the condensing granules of nucleoplasm; 2 There were large amount of Ca〓 in the Golgi complex of spermatid in Golgi phase. The Ca〓 in the acrosomal vesicle were probably from the Golgi complex; 3 Ca〓 was probably concerned with adherence of the acrosomal vesicle to the nuclear membrane.

发现（1）。Ca〓与精子形成过程中染色质的致密化有关，圆形精子细胞局部致密化的染色质团块周围及其内部和长形精子处于的致密化过程的核内均具有较多的Ca〓；（2）。

Eukaryotic genomes are packaged into a nucleoprotein complex known as chromatin, which affects most processes that occur on DNA.

真核基因组被包装到叫做染色质的一个核蛋白复合体中，它影响了发生在DNA上的大部分过程。

This result suggests that cytomixis occurred at synizesis stage may produce some kind of stress which results in activation of retrotransposon to insert into a new locus, or/and breakage rearrangement at the site of retrotransposon in genomic DNA, that both can be detected by fingerprinning.

分析认为在兰州百合减数分裂前期Ⅰ的凝线期时，由于染色质的胞间运动造成对基因组DNA的胁迫，导致了逆转座子del的激活，所插入的位点序列即为所检测到的特异片段；或者是由于染色质的胞间运动造成染色体的断裂重排。

At the early stage of 〓 incubation, the mitochondrias were hyperplasia and swelling. After that the mitochondrias became vacuolation.

砷剂孵育早期即可见线粒体增生和肿胀，线粒体的改变早于细胞核染色质的变化。

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。
