Homework Answers
Ans 2- Each DNA molecule inside the cells contains two strands joined together by hydrogen bonds. Change in conditions can "denature" the DNA and cause these strands to separate. Adding strong bases, like NaOH, increases the pH, thus decreasing the hydrogen ion concentration of the solution and denaturing double-stranded DNA.
Ans 3- The helical structure of double-stranded DNA is destabilized by increasing temperature. Above a critical temperature (the melting temperature), the two strands in duplex DNA become fully separated.
Ans 4- Yes, the results would be affected if the DNA is chemically sheared. Shearing results in random breakpoints and so generates a smear of DNA on a gel.

Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...

please answer all parts I am trying to check my
answers.
Recrystallization of Acetanilide Recrystallization is an important method used by chemists to purify solid compounds. When a chemist conducts a chemical reaction as shown in Scheme 1, it will rarely go to 100% completion, and will frequently produce byproducts. These byproducts and some of the unreacted starting materials will be present in the end as impurities. Chemists need ways to remove these unwanted impurities so they can isolate their...

The question should be a conceptual question that demonstrates a
higher level application of knowledge like; "How does your data
demonstrate the role of entropy and order in the river system in
general?", or "Comparing your results to the results of your
electrophysiology experiment discuss how these systems change in
response to experience." Specifically, this is about synthesizing
ideas applying the results to a novel situation. You could...
