Sample A: Pure protein sample has Abs280 of 0.65 and Abs260 of 0.18, and the e280 is 42,300 M-1cm-1 Sample B: Pure DNA sample has Abs280 of 0.52 and Abs260 of 0.87, and the e260 is 39,880 M-1cm-1 Sample C: The purified protein-DNA complex has an Abs280 of 0.345 and Abs260 of 0.153. You then purify the Protein-DNA complex and come up with a new Sample C whose 260 nm and 280 nm absorbances are given. Based on these data, what are 1) the stoichiometry of the complex. i.e. how many proteins are there for every DNA, and 2) what is the concentration of complex in this sample?

Q7. (a) Devise ladder programs for the following systemCount 10 objects passing along a conveyor belt and close a deflecting gate when that number have been deflected into a chute, allowing a time of 5 s between the tenth object being counted and closing the deflector. (b) Devise ladder programs for a system that will carry out the following tasks: Start a machine if switch B is closed with in 0.5 s of switch A being closed; otherwise, the machine is not switched on. (c) A PID controller has $K_p = 2$, $T_i = \frac{5}{22}$ second and $T_D = 4$ second. Draw the plot of controller output for the following figure. Show all the associated calculations.

A multiple linear regression model based on a sample of 19 weeks is developed to predict standby hours based on the total staff present and remote hours. The SSR is 30,186.31 and the SSE is 37,618.75. Complete parts (a) through (d) below. a. Determine whether there is a significant relationship between standby hours and the two independent variables (total staff present and remote hours) at the 0.05 level of significance. What are the correct hypotheses to test? $H_0: \beta_1 = \beta_2 = 0$ $H_1: \text{At least one } \beta_j \neq 0, j = 1, 2$ Calculate the test statistic. FSTAT = 6.42 (Round to two decimal places as needed.) Determine the p-value. The p-value is (Round to four decimal places as needed.)
