In Chapters 7 and 8, you were introduced to Kayla Tanner, a 45-year-old mother of four who had suffered a dislocated right hip in the bus accident on Route 91. Six weeks after the injury, Mrs. Tanner reported that she was still unable to walk or run without hip pain, and had weakness in her hip, knee, and ankle. Mrs. Tanner walked with a limp that her doctors attributed to weaknesses in flexion at the knee, inversion of the foot, and plantar flexion.

Electromyography (which measures muscle electrical activity) and nerve conduction studies (which measure the speed of nerve impulses) revealed that Mrs. Tanner’s sciatic nerve had been damaged as a result of her injuries—most likely as a result of the nerve being compressed when the hip was dislocated. This large nerve innervates a large number of lower limb muscles. Since her surgery, Mrs. Tanner has been undergoing intense physical therapy and has shown significant improvement.

In order to assess the function and strength of a specific muscle, a physical therapist will often apply resistance (push against the moving limb) to mimic the action of an antagonist muscle. What is an antagonist muscle, and why would the therapist mimic its action?

Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase
Molecular Biology Please help and there is an attached image. Thank you. A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.
Molecular Biology Please help. Thank you. Discuss/define the following:(a) poly A polymerase (b) trans-splicing (c) operon
