Dendrite Cell body Axon Nervous tissue senses stimuli and transmits signals called nerve impulses from one part of an animal to another. It has a cell body, containing the cell's nucleus, and several slender extensions. One type of extension, called a dendrite, conveys signals from its tip toward the rest of the neuron; another type, the axon, transmits signals toward another neuron or to a muscle cell.

In some cases, the proto-oncogene itselfbecomes amplified up to hundreds of times in a cancer cell.An example is the cyclin D1 gene, which is amplified in somecancers. In other cases, the proto-oncogene may be mutatedin a limited number of specific ways, leading to alterations inthe gene product’s structure. The ras gene is an example of aproto-oncogene that becomes oncogenic after suffering pointmutations in specific regions of the gene. Explain why thesetwo proto-oncogenes (cyclin D1 and ras) undergo such differentalterations to convert them into oncogenes

Genesthat cause cancer when they mutate are called oncogenes. Chemotherapy is effective against many tumorsbecause it targets rapidly dividing cells and kills them.Unfortunately, chemotherapy has many side effects,such as hair loss or nausea, because it also kills many ofour normal cells that are rapidly dividing, such as thosein the hair follicles or stomach lining.Many scientists and large pharmaceutical companiesare excited about the prospects of exploiting theRNAi pathway to selectively inhibit oncogenes in lifethreatening tumors. Explain in very general terms howgene-silencing therapy might work to treat cancer andwhy this type of therapy would have fewer side effectsthan chemotherapy

Mutations in an autosomal gene in humans cause aform of hemophilia called von Willebrand disease(vWD). This gene specifies a blood plasma proteincleverly called von Willebrand factor (vWF). vWFstabilizes factor VIII, a blood plasma protein specified by the wild-type hemophilia A gene. Factor VIIIis needed to form blood clots. Thus, factor VIII is rapidly destroyed in the absence of vWF.Which of the following might successfully be employed in the treatment of bleeding episodes in hemophiliac patients? Would the treatments workimmediately or only after some delay needed forprotein synthesis? Would the treatments have only ashort-term or a prolonged effect?
