Which action would not affect gene expression in a eukaryotic cell?
A) Deletion of a promoter
B) Deletion of an enhancer
C) Lack of modification of the cap structure on mRNA
D) Inability of a transcription factor to bind the promoter
E) Deletion of a DNA ori site

Question

Quizplus · Accepted Answer

Deletion of a DNA ori (origin of replication) site would not affect gene expression directly. Ori sites are crucial for the initiation of DNA replication, not for the transcription or translation processes that lead to gene expression. The other options (A, B, C, D) directly impact the transcriptional activity or mRNA stability/modification, thereby affecting gene expression.
