| 1. | Chromosome material with exhibits of such behaviour is called heterochromatin .
表现这种现象的染色体物质叫做异染色质。 |
| 2. | Heterochromatin has shown to be composed largely of short repeated polynucleotide sequences .
异染色质大部分是由短而重复的多核苷酸序列所组成的。 |
| 3. | Heterochromatic areas tend to stain intensely during interphase, sometimes forming condensed masses called chromocentres .
异染色质部分在间期有染色很浓的倾向，有时形成浓缩的块状，这些块状叫做染色中心。 |
| 4. | The origin of such large amounts of constitutive heterochromatin and their role in karyotype evolution and speciation remain a mystery .
如此大量的结构异染色质的来源及其在染色体组型进化和物种形成中的任务仍是一个谜。 |
| 5. | Aberration analysis of chromosome 9 heterochromatin
9号染色体异染色质区的变异分析 |
| 6. | The mitochondria expanded and vacuolated and its cristae disappeared ; the double membrane was broken
细胞核形状不规则，核膜破损，异染色质聚集突出，核物质外流。 |
| 7. | Euchromatin is thought to be actively involved in transcription and therefore protein synthesis , while heterochromatin is inavtive
异染色质由于折叠压缩程度高，所以被碱性染料染色时着色较深。 |
| 8. | Cells take diverse shapes . these are epithelial cords of block - like cells . as always , nucleoli and nuclear heterochromatin stain darkly with hematoxylin
不同形态的细胞。这些是立方细胞排列成的上皮索状结构。总之，核仁与细胞核中的异染色质被苏木精染成深色。 |
| 9. | Most ones were these disorganized partly , mainly , till all , mitochondria fused by itself , circled , mitochondria membrane broke and disintegrated
处理20d后，细胞核与线粒体受损情况加重，主要表现在，细胞核膜间距加大，异染色质疑聚，常染色质电子密度降低。 |
| 10. | During this process , a series of modification appeared on the xi , which led to the formation of stable heterochromatin that can be inherited steadily in cell duplication
失活的染色体上面往往发生一系列的修饰，导致产生非常稳定的异染色质且能在细胞复制的过程中稳定遗传。 |
