Heterogeneous nuclear RNA (hnRNA) can contain all the following EXCEPT
A) sequences which can base pair with small nuclear RNA (snRNA).
B) sequences derived from the TATA region of the promoter.
C) introns.
D) polyadenylate.
E) codons.

Question

Quizplus · Accepted Answer

The TATA region of the promoter is not part of the hnRNA. hnRNA is the precursor to mRNA and contains introns, exons, and sequences that can base pair with snRNA, and it is often polyadenylated, but it does not include promoter sequences like the TATA box, which are upstream of the transcription start site and not transcribed into RNA.
