What components of DNA (other than the one Dische/s reagent reacts with) could you test for to confirm that you extracted DNA and not another biopolymer? What tests would you use?
(Test=DNA extraction from strawberries)

Can you pleasee answer these questions regarding the experiment of DNA quantification. What is “blank” and why do we use it in DNA quantification? If you are told to analyze DNA samples that we extracted from buccal swabs, what would you use as a blank? 3. Explain in details: a. Concentration b. A260/A280 ratio c. A260/A230 Why are those measurements used, how do you know which concentration to expect if you used the commercial kit for DNA extraction, what is...
Given your compounds (1-hexyne and Hexane) – name one other type of test or reaction you could have performed given the functional group, that would have helped identify your unknowns. One test per unknown. Tests performed: Br2, Tollens test, Chromic test, Lucas test. We are looking for at least 2 other tests, one per unknown, (not Bromine, lucas, tollen, silver nitrate and chromic) that could help determine our unknowns (1-hexyne and hexane)
1.Where in the separation procedure could you lose one or more of the panacetin components? Explain which component could be lost in which step. 2.In the separation scheme, the dichloromethane solution is extracted with sodium bicarbonate. What would happen if the dichloromethane solution was extracted with hydrochloric acid instead (which has actually happened)? Would the separation scheme still work? Explain your reasoning 3. Acetaminophen (the active ingredient in Tylenol) is insoluble in water, soluble in sodium hydroxide solution, insoluble in...
Suppose you filled one test tube with alanine and a second test tube with casein, but forgot to label the test tubes. What test could you run on the samples to confirm which test tube contained the alanine? Explain.
Question 10.20 From the drop-down lists below select the reagent(s) you could use to convert cyclopentene to the compound below using the fewest possible steps. More than one step may be necessary. If a second step ?s not needed, leave the entry for step 2 blank. (Note: The same reagents are available for steps 1 and 2.) Step1: Step 2:
1 and 2 please 1. Explain why you would conduct a t test rather than a z test. In other words, what is the difference between a one sample t test and a one sample z test? 2. Because of what is discussed in question 1, some of the components of calculating at value are different from the components of a z value. Specifically, the t value utilizes degrees of freedom. Explain what degrees of freedom means (you can include...
In this exercise, you will use two reagent mixtures to test a variety of organic halides. The distinct differences in the factors affecting the SN2 and SN1 mechanisms make it possible to determine which mechanism is favored by a given compound. One reagent and solvent favors SN2 reactivity, the other SN1 reactivity. From the results of your tests, you will determine which mechanism, if either, is favored by a given compound. In your post-lab assignment, you will be required to...
The probability that a certain kind of component will survive a shock test is .8. 1. Find the probability that exactly 2 of the next 6 components you test will survive. 2. What is the probability that you must test 8 components to find two that fail? 3. What is the probability that the 4th component you test is the first one that fails the test? 4. Out of a group of 100 components, 20 would fail a shock test....
properties of alcohol 5. Using the tests performed in this experiment, how could you distinguish between the following pairs of compounds? Tell what reagent or test you would use and what you would observe. 1-Butanol and 2-butanol a) b) C Isobutyl alcohol and tert-butyl alcohol 1-Propanol and 1-heptanol Cyclohexanol and cyclohexane d)
Professor Blockhus gives two different statistics tests, but one test is harder than the other. Scores on test A are normally distributed with a mean score of 78 and a standard deviation of 6. Scores on test B are also normally distributed but with a mean score of 65 and a standard deviation of 9. If Erik scored an 79 on test B, what percent of the class scored below him? That is, what is his percentile on test B.
