Question

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) Enhancer
b) Promoter
c) Silencer
d) Operator

Answer 1

Enhancers are the DNA regulatory sequences that make coordinated gene expression possible in eukaryotes.

Step-by-step explanation:

In eukaryotes, coordinated gene expression is made possible by DNA regulatory sequences called enhancers. Enhancers are binding sites for activator proteins, which can be located far away from the genes they regulate. These activators interact with transcription factors and mediator proteins to enhance transcription of the target genes.
