The bacterial host will lyse immediately Infection will proceed as usual Early genes will not be translated Middle genes will not be transcribed The bacterial host will lyse immediately Infection will proceed as usual Early genes will not be translated Middle genes will not be transcribed ANSWER DOWNLOAD EXAMIANS APP
Genetic Regulation Prokaryotes Why are several structural genes regulated as a unit in bacteria? 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 None of these ANSWER DOWNLOAD EXAMIANS APP
