4. If the lane containing the DNA from the undigested lambda sample (U, uncut) has no band, what can you conclude? Please provide 2 possible conclusions. 5. After running your agarose gel, you analyze your gel and see that your PSTI lane looks like the "U" uncut control lane. Is this expected? Explain. 6. You decided to perform your digests at room temperature instead of 37(C. Will your gel look the same as your friend's gel who performed the digests at the correct temperature? Explain why and what your gel will look like.

1) When the relevant cost index seven years ago was 135, a nuclear centrifuge cost \$47,000. The centrifuge had a capacity of separating 3200 gallons of ionized solution per hour. Today it is desired to build a centrifuge with capacity of 7,600 gallons per hour, but the cost index now is 420. Assuming a power-sizing exponent to reflect economies of scale, $x$, of 0.61. Use the power sizing model to determine the approximate cost (expressed in today's dollars) of the new reactor.
