Genetic Regulation Prokaryotes Why are several structural genes regulated as a unit in bacteria? None of these An accident of evolution The bacteria chromosome is so small; many different genes must be controlled by the same promoter It allows coordinating regulation of genes with a common function None of these An accident of evolution The bacteria chromosome is so small; many different genes must be controlled by the same promoter It allows coordinating regulation of genes with a common function ANSWER DOWNLOAD EXAMIANS APP
