Question

Quizplus · Accepted Answer

Transcriptional control influences the amount and kinds of mRNA assembled from structural genes.

Answer: B
 Splicing, capping, and adding a poly-A tail are part of post-transcriptional modifications of mRNA.

Answer: C
 The nuclear envelope selectively regulates the passage of transcripts through the nuclear pores.

Answer: D
 Phosphorylation of proteins happens after translation is complete and is not related to transcriptional control.

Answer: E
 Dosage compensation is related to the process of equalizing gene expression of X-linked genes in males and females and is not related to transcriptional control in general.
