The Human Genome Project resulted in the identification of 20,000 genes that code for proteins in humans. On average, each gene can code for 4 different proteins. Which of the following processes explains how a single gene could code for more than one protein? A) the central dogma of molecular biology B) mutations C) alternative splicing D) redundancy in the genetic code E) the fact that there are three stop codons

A biology professor at a prestigious university stated to his introductory class that "Today, a basic understanding of DNA and genetics is as important as a basic understanding of computers and the internet."Based upon what you have learned about DNA and gene expression in this module, how could you make a case to support this statement?

Your friend has discovered that the same human promoter is responsible for producing two different proteins. In Kidney cells it is responsible for the production of protein A while in Brain cells it is responsible for the production of Protein B. Your friend has concluded that this promoter must be controlling two different genes. Do you agree or disagree with your friend's conclusion? Explain why or why not. Be sure to describe the molecular events to support your answer.
