Which of the following methods is utilised by eukaryotes to control their gene expression that is different from the type of control found in bacteria?
A) control of chromatin remodelling
B) control of RNA splicing
C) transcriptional control
D) control of both RNA splicing and chromatin remodelling

Question

Quizplus · Accepted Answer

Eukaryotes have additional mechanisms to control their gene expression that are not present in bacteria. One of these mechanisms is the control of RNA splicing, which allows eukaryotes to produce multiple different proteins from a single gene. The other mechanism is the control of chromatin remodelling, which allows genes to be activated or repressed by changing the accessibility of the DNA to transcription factors. Therefore, the correct answer is D, which includes both RNA splicing and chromatin remodelling as methods that eukaryotes use to control their gene expression. Transcriptional control is also found in both bacteria and eukaryotes, so it is not a different type of control.
