Problem 2: X-ray diffraction: (a) Determine the maximum wavelength for which constructive interference can be observed in the Bragg model for a simple cubic crystal with a lattice constant of 3.6 A. (b)What is the energy of the X-rays in electron volts? (c) If you were to perform neutron diffraction, what would the energy of the neutrons have to be in order to obtain the same de Broglie wavelength? (d) You could argue that if you take X-rays with twice...
Below is data that a researcher collected on the observed decay of a chemical in water as a function of time. The Researcher used an analytically technique to quantify the chemical that reports relative “peak area” or “response” values. As a result, the researcher analyzed a series of known “standards” of chemical “A” to construct a standard curve, from which the concentrations of “A” in the experimental samples could be calculated. It is known that the chemical decays by a...

QUESTION 6 Assume you are studying a protein-coding gene, ACEX, which includes 4 exons as illustrated in the gene map below. The 5' UTR and 3' UTR segments are each 25 bp long. Exons 1 thru 4 are 100, 200, 300, 400 bp long, respectively. Each intron is 200 bp each. The locations of the relevant EcoRI sites within the ACEX locus are indicated, but the location of other restriction enzyme sites (like BamHI) are not shown." EcoRI probe EcoRI...
