  1. A very well-known author, Dan Green was visiting a friend to talk about topics for a new book. The friend, Mr. Snoop said that he had been at a party when he heard about something called the Da Vinci Code. Mr. Snoop told Green all about the Da Vinci Code. Green was very excited and rushed to his office. Over the next two days, Green wrote a book called the La Vinci Code. After the book was released to stores around the country, Green sold all rights to BS Studio. BS Studio made a TV movie from the book, which changed the location setting from Paris to Fullerton and changed the character names.Discuss all legal issues

On its income statement for a recent year, Continental Airlines, Inc. reported a net loss of $68 million from operations

On its income statement for a recent year, Continental Airlines, Inc. reported a net loss of $68 million from operations. On its statement of cash flows, it reported $457 million of cash flows from operating activities.

Explain this apparent contradiction between the loss and the positive cash flows.

If changing the pH of an enzyme solution greatly reduces the activity of that enzyme without precipitation, how could you tell in the lab if the result of denaturation or just going to a pH that is just not a good one for the enzyme? And how would a change in pH impact or even stop enzyme function without denaturation? (consider the enzymes that are active in your stomach, such as pepsin)

  1. Does your result match what you had expected based on how you know enzyme activity is affected by temperature? Explain.
  2. What changes would you make to improve this experiment? Provide at least one suggestion for improvement.
  3. What could you do to increase enzyme activity in this experiment? Provide at least one suggestion.
  4. Do animals have an enzyme that breaks down hydrogen peroxide? How could you test for the presence of such an enzyme?
  5. What changes would you make to this experiment to determine the optimal temperature for this particular enzyme? Do a web-search to find the optional temperature for this enzyme. Include references to information sources.

1.

Which of the following is correct about why bacteria colony are blue verses white following ligations of PCR product into pGEM-T Easy plasmid and transformation?

A.

White colonies have no PCR insert in the plasmid and a functional B-galactosidase enzyme, while blue colonies have a non-functional B-galactosidase enzyme with a PCR insert.

B.

White colonies have a PCR insert in the plasmid and a non-functional B-galactosidase enzyme, while blue colonies have a functional B-galactosidase enzyme with no PCR insert.

C.

White colonies have no PCR insert in the plasmid and a non-functional B-galactosidase enzyme, while blue colonies have a functional B-galactosidase enzyme with a PCR insert.

D.

White colonies have a PCR insert in the plasmid and a functional B-galactosidase enzyme, while blue colonies have a non-functional B-galactosidase enzyme with no PCR insert.
