In eukaryotes,control of gene expression is NOT by
A)translational control in cytoplasm after mRNA leaves the nucleus and before protein is produced.
B)transcriptional control in the nucleus based on which genes are transcribed and how fast they are transcribed.
C)posttranscriptional control in the nucleus after DNA is transcribed,including the speed with which mRNA leaves the nucleus.
D)posttranslational control in the cytoplasm that occurs after protein synthesis.
E)the use of repressor proteins and operators.

Question

Quizplus · Accepted Answer

The use of repressor proteins and operators is a method of control of gene expression in prokaryotes, but not in eukaryotes. In eukaryotes, control of gene expression occurs mainly at the transcriptional and posttranscriptional levels, as well as at the posttranslational level.
