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 An accident of evolution It allows coordinating regulation of genes with a common function The bacteria chromosome is so small; many different genes must be controlled by the same promoter None of these An accident of evolution It allows coordinating regulation of genes with a common function ANSWER DOWNLOAD EXAMIANS APP
Genetic Regulation Prokaryotes Enhancers differ from promoters in that they initiate transcription their orientation can be inverted without effect they are adjacent to the start codon they are restricted to a specific gene they initiate transcription their orientation can be inverted without effect they are adjacent to the start codon they are restricted to a specific gene ANSWER DOWNLOAD EXAMIANS APP
