Question
____ are found in prokaryotic DNA only, and contain groups of genes that are regulated together.
Answer
Operons are found in prokaryotic DNA only, and contain groups of genes that are regulated together.
The advantage is that a group of genes whose products are all needed for a common function can be transcribed together
Operons contain activators, inducers, and repressors
Example: The lac operon contains genes that E. coli uses for metabolizing the sugar lactose. Do not forget that bacteria exists in humans, but not human cells since human cells are eukaryotic.
