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