| 1. | The dna of chromatin must replicate before cell division .
染色质DNA在细胞分裂之前必须复制。 |
| 2. | 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。 |
| 3. | That which shows the "normal" condensation pattern is called euchromatin .
那些表现“正常的”浓缩格式的部分叫做常染色质。 |
| 4. | Zones of loosely arranged euchromatin are located mainly in the center of the nucleus .
疏松的染色质区带主要位于细胞核的中心部。 |
| 5. | In this condition, they are sometimes referred to collectively as the chromatin of the nucleus .
在这种情况下，人们有时笼统地称它们为核染色质。 |
| 6. | 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。 |
| 7. | A more complicated particle called the chromosome is apparently the fundamental unit of assembly .
一个更复杂的微粒，称为染色质体，显然是包装的基本单位。 |
| 8. | In human epithelial cells, sex chromatin appears as a small granule attached to the nuclear envelope .
在人的上皮细胞中，性染色质象个小颗粒，连在核膜上。 |
| 9. | 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。 |
| 10. | 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。 |
