Mutations in genes can lead to changes in protein function, which can affect an organism's traits or cause diseases. Genes can be regulated by various mechanisms to ensure proper expression at the right times and in the right cells. In prokaryotes, genes are often organized into operons, allowing coordinated regulation of related genes. Review Questions What is the role of a gene in protein synthesis? How can mutations in a gene affect an organism? What mechanisms regulate gene expression?
