Choose the one most appropriate answer for each.
-Transport control

B)Splicing, capping, and adding a poly-A tail
C)Nuclear envelope selectively regulates passage of transcripts
D)Phosphorylation of translated protein
E)Dosage compensation

Question

Quizplus · Accepted Answer

Transport control refers to the process by which mRNA molecules are selectively transported out of the nucleus and into the cytoplasm. This is regulated by the nuclear envelope, which determines which transcripts are allowed to pass through its pores.

Answer: E
 Dosage compensation refers to the equalization of gene expression between males and females in species with sex chromosomes. This is achieved through various mechanisms, such as the inactivation of one X chromosome in females (X-inactivation) or the upregulation of X-linked genes in males.

Neither A, B, nor D are appropriate answers for the definition of transport control. Option A refers to transcriptional control, option B refers to post-transcriptional modification, and option D refers to post-translational modification.
