| 1. | The second chromosomal abnormality is called heterochromatin repulsion ( HR ).
|
| 2. | Methylation at lysine 9 is associated with transcriptional repression and heterochromatin.
|
| 3. | Facultative heterochromatin is the result of genes that are RNAi.
|
| 4. | It is not repetitive and shares the compact structure of constitutive heterochromatin.
|
| 5. | The regions that stain darker are regions of constitutive heterochromatin.
|
| 6. | The three most common modifications in constitutive heterochromatin are heritable.
|
| 7. | More condensed ( tightly packed ) DNA is referred to as heterochromatin.
|
| 8. | During cell division, heterochromatin formation is required for proper chromosome segregation.
|
| 9. | The inner plate appears like a discrete heterochromatin domain throughout the cell cycle.
|
| 10. | Visualization of constitutive heterochromatin is possible by using the C-banding technique.
