| 31. | The mature r-proteins are then " imported " back into the nucleus and finally the nucleolus.
|
| 32. | The best-known of these is the nucleolus, which is mainly involved in the assembly of ribosomes.
|
| 33. | In this way, macromolecules with a molecular weight up to 2000 kDa are easily distributed throughout the nucleolus.
|
| 34. | Treacle is active in the nucleolus, which is a small region inside the nucleus where rRNA is produced.
|
| 35. | They are usually located in the nucleolus of the eukaryotic cell which is a major site of snRNA biogenesis.
|
| 36. | EBER1 associates with human ribosomal protein L22 and causes this protein to move from the nucleolus to the nucleoplasm.
|
| 37. | The nucleolus is the largest sub-organelle within the nucleus and is the principal site for rRNA transcription.
|
| 38. | A continuous chain between the nucleoplasm and the inner parts of the nucleolus exists through a network of nucleolar channels.
|
| 39. | This collecting nucleolus was easily visible in phase contrast even without pretreatment due to its large size and particular structure.
|
| 40. | The rRNA is transcribed, at a high speed, in the nucleolus, which contains all 45S rRNA genes.
