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 An accident of evolution It allows coordinating regulation of genes with a common function None of these The bacteria chromosome is so small; many different genes must be controlled by the same promoter An accident of evolution It allows coordinating regulation of genes with a common function None of these ANSWER DOWNLOAD EXAMIANS APP
