Genome complexity: DNA repair mechanisms (Introduction)

DAVID: The Nobel prize in chemistry goes to three scientists who worked out a major part of an incomplete story of excision of DNA when a mismatch occurs in cell division and DNA copying:-http://www.nobelprize.org/nobel_prizes/chemistry/laureates/2015/popular-chemistryprize2...-DAVID: This is an excellent article in lay terms with great diagrams. Just remember that the enzymes used are giant molecules, which raises the obvious question: if chance evolution is true, how did evolution find each very specialized molecule made up of thousands of amino acids and trace metals?-Thank you for a great article describing an amazing process. It brings home to us the vast scale of the micro-world that lives inside us. There are billions of little workers cooperating night and day to keep our bodies functioning, and they constantly adjust to every move we make. How did they get together in the first place? As always, I agree with you that chance stretches credulity beyond its limits. Perhaps they did it by using their (God-given?) intelligence? If we rid ourselves of our “large organisms chauvinism” (Shapiro) and acknowledge the possibility that just as we are intelligent specks in a vast universe, the specks in our bodies are also beings with their own form of intelligence, the whole process makes sense.
 
DAVID (under “ant colony complexity”): Still 50/50. Just as likely I am right and lots of folk agree with me. I know how automatic my cells are in my human body. -You “know”? It's worth recalling Stephen Talbott's observation: “We discover that our highest capacities - our thinking, our formulation of goals and plans, our strivings and passions, our sense of well-being and illness - are objectively imaged in our own biological organism right down to the molecular activity of our cells, as also in the cells of every other living creature.” (My bold). But you “know”?
