| 21. | Evolutionary dynamics of segmental duplications from human Y-chromosomal euchromatin / heterochromatin transition regions.
|
| 22. | When genes are placed near a region of constitutive heterochromatin, their transcription is usually silenced.
|
| 23. | The quantity and distribution of heterochromatin among both X chromosomes and autosomes is different as well.
|
| 24. | It is a megastructure containing several siRNA which use the RNAi pathway to regulate heterochromatin formation.
|
| 25. | The mechanism by which the RITS complex induces heterochromatin formation and organization is not well understood.
|
| 26. | The heterochromatin can spread stochastically and switch off the color gene resulting in the white eye sectors.
|
| 27. | It specifically stains constitutive heterochromatin, which are regions of the chromosome at or near the centromere.
|
| 28. | Overall, it plays a vital role in heterochromatin organization, chromosome segregation, and mitotic progression.
|
| 29. | This suggests that facultative heterochromatin interacts with the polycomb repression complex in order to limit lytic reactivation.
|
| 30. | Heterochromatin protein 1 ( HP1 ) binds both chromatin and the LBR . ONM, outer nuclear membrane.
