Choose all that apply.
The tandem arrays of 5S rRNA genes are located in an NOR.
The 45S pre-rRNA transcript is processed by complexes of RNA and protein known as snoRNPs.
RNA Polymerase II transcribes the 5S rRNA genes.
The 45S rRNA genes have very strong promoters for optimal transcription.
No productive association of the small and large ribosomal subunits occurs until the subunits are exported into the cytoplasm.
The 45S and 5S rRNA genes are located on chromosomes 13, 14, 15, 21 and 22.
