Which of the following mechanisms is used to coordinate the expression of multiple, related genes in eukaryotic cells?
A) Environmental signals enter the cell and bind directly to promoters.
B) A given gene may have multiple enhancers, but each enhancer is generally associated with only that gene and no other.
C) The genes are organised into a large operon, allowing them to be coordinately controlled as a single unit.
D) A single repressor is able to turn off several related genes.

Question

Quizplus · Accepted Answer

Eukaryotic cells often coordinate the expression of related genes by having multiple enhancers associated with a given gene. These enhancers may be located far away from the gene in question, but still regulate its expression. This allows for fine control of gene expression and ensures that related genes are expressed together in the appropriate tissues and conditions. Options A, C, and D are not accurate mechanisms for coordinating the expression of multiple, related genes in eukaryotic cells.
