A series of Hfr strains that have genotype m n o p q r are mixed with an F-strain that has genotypem-n-o-p-q-r-. Conjugation is interrupted at regular intervals and the order of appearance of genes from the Hfr strain is determinedin the recipient cells. The order of gene transfer for each Hfr strain is:Hfr5: m+ q+ p+ n+ r+ o+ Hfr4: n+ r+ o+ m+ q+ p+ Hfr1: o+ m+ q+ p+ n+ r+ Hfr9: q+ m+ o+ r+ n+ p+What is the order of genes on the circular bacterial chromosome?

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.)
