Genetic Regulation Prokaryotes Enhancers differ from promoters in that they initiate transcription they are adjacent to the start codon they are restricted to a specific gene their orientation can be inverted without effect they initiate transcription they are adjacent to the start codon they are restricted to a specific gene their orientation can be inverted without effect ANSWER DOWNLOAD EXAMIANS APP
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
