Transcription of the Major Fraction of Ribosomal RNA in Eukaryotic

Transcription of the major fraction of ribosomal RNA in eukaryotic cells

A) occurs in the nucleoplasm, outside of the nucleolus.
B) involves transcription from a gene which occurs twice in a diploid cell.
C) leads to a large precursor which is processed by methylation and cleavage.
D) would be inhibited by puromycin but not by actinomycin D
E) none of the above.
