Which does not apply to the post-transcriptional processing of ribosomal RNA?
A)The subunits of rRNA are produced in equal amounts since they originate from the same transcript.
B)tRNA precursors are sometimes cleaved from the primary transcript of rRNA precursor.
C)A polyA tail is added to the 5' end of the 30S subunit.
D)After initial cleavage of the primary transcript,specific endonucleases trim nucleotides from the ends of rRNA molecules.

A polyA tail is not added to the 5' end of the 30S subunit during post-transcriptional processing of ribosomal RNA. This statement is incorrect, and so does not apply to the process. The other statements are all true for the post-transcriptional processing of ribosomal RNA. The subunits of rRNA are produced in equal amounts, tRNA precursors are sometimes cleaved from the primary transcript of rRNA precursor, and specific endonucleases trim nucleotides from the ends of rRNA molecules after initial cleavage of the primary transcript.
