Final answer:
GAL4 enhancers can be located upstream, within the coding region, or downstream of the genes they regulate. They are known as distal cis-elements.
Step-by-step explanation:
The GAL4 enhancers can be located upstream, within the coding region, or downstream of the genes they regulate. They can also be thousands of nucleotides away from the genes. The GAL4 enhancers are known as distal cis-elements.
