A company that produces fine crystal knows from experience that 13% of its goblets have cosmetic flaws and must be classified as "seconds." (Round your answers to three decimal places.) USE SALT (a) Among eight randomly selected goblets, how likely is it that only one is a second? (b) Among eight randomly selected goblets, what is the probability that at least two are seconds? (c) If goblets are examined one by one, what is the probability that at most five must be selected to find four that are not seconds?

The students conducted the assay for LDH activity using the two serum samples. Each cuvette (path length 1 cm) contained 3ml of a suitable assay buffer (including pyruvate as substrate). 20 microlitres of either serum was added to the cuvette and the absorbance values immediately recorded at the optimum wavelength for a period of 5 minutes (absorbance readings taken every 30 seconds). Protein concentration of serum sample (mg/ml) Change in absorbance at optimum wavelength per minute Control serum (C) 8 -0.04 Diseased serum (D) 7.8 -0.6 1c. Using the molar absorption coefficient of NADH as 6220 M-1 cm-1, and by application of the Beer-Lambert law, estimate the enzyme activity in the two samples (C and D). Express activity as moles per second. 1d. Estimate the specific activity of the two samples (moles per second per microgram).

A solution of DNA of unknown concentration (termed "[unknown] DNA solution") gave an absorbance value of 0.39 at 260 nm. The goal here is to determine the DNA concentration of this [unknown] DNA solution. To calculate this, you are given the following additional information: A DNA solution whose concentration is 50 ug/ml has an absorbance value of 1.0 at 260 nm. Using this information and knowing that A1/C1 = A2/C2 i. Calculate the DNA concentration (ug/mL) in the DNA solution of [unknown] ii. iii. iv. Once you have determined the DNA concentration of [unknown] DNA solution, calculate how many ug of DNA would be present in 25 μl of this DNA solution If you dilute the "[unknown] DNA solution" 10-fold, i.e. 1/10, what will the absorbance value (at 260 nm) of the diluted solution be? What will the new concentration of DNA of the diluted solution be?
