Operon systems are found... A) In prokaryotes B) In Eukaryotes C) In all prokaryotes and eukaryotes D) Only in protozoans E) All of these
Homework Answers
Answer:
A). In prokaryotes
Explanation:
An operon is a collection of genes all under the control of the same promoter. When an operon is transcribed, all of the genes on the operon are on the same mRNA. Operons occur in prokaryotes, but not eukaryotes.
