Q
regions of nucleolus
A
Fibrilar center(FC)
Dense fibrilar component(DFC)
Granular component(GC)
3
Q
most important functions of Nucleolus
A
where rRNAs (5.8S, 18S, 28S) are transcribed and ribosomal subunits are assembled
ribosome biogeresis
4
Q
the fibrillar center
A
where transcription of rDNA occurs
5
Q
the dense finrillar component
A
is where the protein structures necessary for rRNA processing are located
6
Q
the granular component
A
contains another vital protein known as nucleophosmin which participates in the biogenesis of the ribosome
