- The Selfish Gene is a radical theory that argues that all living creatures are essentially vehicles for their genes- hence, we all are a “survival machine" for our genes. In the light of what you have learned about the molecular structure and function of the gene, is this perspective still relevant? Cite specific biological phenomena to prove your point.

Consider the morphology, physiology, ecological, behavioral, etc. aspects of the gene. Discuss each part of the gene listed in your definition. Is your definition of the gene as determined through complementation, recombination, and mutation for prokaryotes directly applicable to eucaryotes? Why or why not?
