What is the Function of Dense Fibrillar Components?
The primary function of the DFC is to facilitate the transcription of rRNA genes and the early stages of rRNA processing. This region is rich in newly synthesized rRNA and nucleolar proteins involved in rRNA processing, such as fibrillarin and nucleolin. These proteins play a critical role in modifying and cleaving pre-rRNA molecules, preparing them for assembly into ribosomal subunits within the GC.
