By restricting the traffic of proteins and RNA across the nuclear envelope, eukaryotic cells can regulate _______ in unique ways.
A) translation and transcription
B) transcription only
C) translation only
D) endocytosis

Question

Quizplus · Accepted Answer

The nuclear envelope separates the nucleus from the cytoplasm and restricts the flow of molecules, including proteins and RNA, between the two compartments. This allows eukaryotic cells to regulate gene expression by controlling the transport of transcription factors and RNA molecules from the nucleus to the cytoplasm, where they can be translated into proteins. Therefore, the restriction of traffic across the nuclear envelope enables regulation of both transcription and translation, making choice A the best answer. Endocytosis is not related to the regulation of gene expression and therefore is not a correct answer.
