Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome. If she moves the operator to the far end of the operon, past the transacetylase (lacA)gene, which of the following would likely occur when glucose levels are low? A. The inducer will no longer bind to the repressor.

B. The lac operon genes will be transcribed continuously.

C. The repressor protein will no longer be produced.

D. The operon will never be transcribed.

E. The repressor will no longer bind to the operator.

The smallest parts of these that retain their original properties are called

Oak and maple trees, chipmunks, white-tail deer, and black bears emerging from hibernation are all organisms that may be found in which biome

Mr. j, age 42, is a construction worker in las vegas. he recently noticed that a mole on his face seemed to be getting larger and darker. at first he did not worry because he was in the sun a lot and assumed the change may have been caused by sunburn. after a month, not only was the mole larger and darker, but it appeared to be “bumpy.” his doctor diagnosed a malignant melanoma skin cancer following biopsy of the nevus. mr. j reports pain in his right shin that does not go away when he puts his feet up or sleeps. discussion questions 1. relate mr. j’s skin changes to the warning signs for malignant melanoma. (see malignant melanoma.) 2. discuss the normal progression of this malignancy. what is the significance of the bone pain that mr. j is experiencing? (see malignant melanoma.) 3. discuss the treatment available for this patient and the prognosis for recovery. (see malignant melanoma.)
