...Carnegie men heated a solution of mouse DNA until its strands separated. Then they mixed it with agar that cooled to a stiff jelly, which immobilized the long strands and kept them from recombining. Next, the jelly was reduced to tiny granules, each charged with mouse...
Code Segments. The scientists then prepared a solution of mouse DNA that had been made radioactive with carbon 14. They chopped the molecules into short sections, each carrying a small part of the mouse genetic code, and separated the two strands. When these were mixed with the chunks of agar, their small size permitted them to diffuse into the jelly, and whenever one of them encountered a trapped strand that had a matching sequence of genetic code, the two segments combined firmly...
...measuring the radioactivity of the recombined DNA, the scientists could estimate closely how many of the segments had found matching partners. Under the best conditions, about 25% of the chopped DNA hooked up with that in the agar. This comparatively high figure was only natural, since both samples came from the same species of animal...
Meanwhile, to keep his chronology straight, Foreman inserts newsreel footage from back home: the Rockettes try out an obstacle course; Shirley Temple marries John Agar; Bess Truman launches a flying ambulance. Cutting back to the action makes for a staccato "new cinema" pace-and for irony, tons and tons of it. Foreman likes his irony set to music. While troop trucks slog through snow, he cuts to a slide announcing: THE MANAGEMENT OF THIS THEATER WISHES EVERYBODY A MERRY CHRISTMAS AND A HAPPY NEW YEAR 1945. EVERYBODY SING! Later, there is mawkish sentiment when some gentle British folk invite Peppard...
