Although operons are not common in eukaryotes, eukaryotic genes may be activated by the same stimulus.Which of the following DNA regulatory sequences makes this coordinated gene expression possible?
A)Core promoter
B)Enhancer element
C)Response element
D)Boundary element
E)Silencer element

Response elements are specific DNA sequences that can be recognized and bound by transcription factors. These transcription factors are activated by certain stimuli, allowing for the coordinated expression of genes that contain the same response element, even if those genes are not physically linked, as is often the case in eukaryotes. This mechanism enables a unified cellular response to environmental changes or signaling molecules.
