How does the organization of related genes into operons enable the coordinated production of proteins?
A) Genes are transcribed from one promoter. Transcription of the various mRNAs can be regulated by one set of activators and/or repressors, and each enzyme translated according to need.
B) Genes are transcribed together from one promoter as a polycistronic mRNA. They can be regulated by one set of activators and/or repressors and enzymes required for a common pathway can be synthesized together.
C) Genes are transcribed together from one promoter as a polycistronic mRNA. They can be regulated by one set of activators and/or repressors. Processing and possible splicing of this mRNA will allow enzymes to be translated according to need.
