Question

Quizplus · Accepted Answer

Genes that encode for stress responses in plants are located farther apart on the chromosome than structural genes in bacterial operons. This is because unlike bacterial operons where all the genes in the operon are transcribed together and translated as a single unit, each gene in plant stress response pathways requires its own promoter and regulatory elements to respond to environmental signals. Therefore, they are not located in close proximity to each other.
