What would happen to the protein if there was a mutation in its promoter region?
The protein would be nonfunctional due to an early stop codon.
RNA polymerase would not bind to the gene, so the protein would not be made.
The protein would be nonfunctional because the mutation would alter the gene's reading frame.
The protein would function normally, since the promoter is upstream of the reading frame.

What was dr. willem johan kolff’s first step in using the scientific process to invent the hemodialysis machine? he built the machine and tried it with various patients, collecting data about its effectiveness. when a patient’s kidneys failed, he wondered if it would be possible to perform kidney functions with an external machine. he researched and collected data about numerous patients who exhibited symptoms of kidney failure. he drew conclusions from studies of various symptoms of kidney failure, and drew a design for the ideal external blood-processing machine.
