Which of the following classifies eukaryotic mRNAs synthesized in the nucleus?
A)poly(A)RNAs
B)intervening RNA sequences
C)heterogeneous nuclear RNAs
D)RNA exons

Question

Quizplus · Accepted Answer

Eukaryotic mRNAs are initially synthesized in the nucleus as heterogeneous nuclear RNAs (hnRNAs), which undergo post-transcriptional processing to produce mature mRNA that can exit the nucleus and be translated into protein. Poly(A)RNAs refer to the polyadenylated tail added to the 3' end of mature mRNA, while intervening RNA sequences and RNA exons refer to the different regions of pre-mRNA that are removed or spliced together during post-transcriptional processing.
