Question

How can eukaryotic structural genes involved in shared metabolic functions be coordinately (at the same time) expressed? by transcription factors that recognize shared consensus sequence in promoters. by several transcription factors that are coded by similar regulatory genes. by the presence of structures analogous to bacterial operons By sharing enhancers
help please

Answer 1

-correct answer can be --By several transcription factors that are coded by similar regulatory genes.

Some statement prove it

Gene expression in eukaryotes is normally believed to be controlled by transcriptional regulators that activate genes encoding structural proteins and enzymes.

A complex set of interactions between genes, RNA molecules, proteins (including transcription factors) and other components of the expression system determine when and where specific genes are activated and the amount of protein or RNA product produced.

Some genes are expressed continuously, as they produce proteins involved in basic metabolic functions.

Gene regulation of the lac operon was the first genetic regulatory mechanism to be understood clearly, so it has become a foremost example of prokaryotic gene regulation.( this say that analogous structures of bacteial lac operon cant be a part of eukaryotic structural gene)
