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

Genetic Regulation Prokaryotes Tubulin is regulated by binding of tubulin to tubulin mRNA splicing of the tubulin transcript binding of tubulin to DNA binding of tubulin to the tubulin translational product binding of tubulin to tubulin mRNA splicing of the tubulin transcript binding of tubulin to DNA binding of tubulin to the tubulin translational product ANSWER DOWNLOAD EXAMIANS APP
