Examples
- In most eukaryotes, nucleolar organizer regions are important for the formation of the nucleolus.
- The primary functions of nucleolar organizers during interphase involve transcription of ribosomal RNA genes.
- During mitosis, the chromosomes undergo condensation and the nucleolar organizer regions become closely associated with each other.
- Research shows that variations in nucleolar organizer structure often correlate with cell type and function.
- Nucleolar organizers are specialized chromosomal regions that control ribosomal gene expression during cell division.
