47. How gene regulation makes our life possible

Do you have mutant super powers like eating ice cream without it hurting your stomach? How can diet and exercise slow down aging, or why do age in the first place? Does what happen to you affect your children? How do we make more proteins than we have protein-coding genes for?  Lastly, how can two black labs have both chocolate and yellow lab puppies? We can find answers to these questions by knowing how our genes are regulated. I discuss gene regulation including operons, alternative mRNA splicing, epistasis, and epigenetics,
