Select one of the multiple choice questions you answered for this exam.  List the number (1-34) of that question here, and then give a brief explanation for your answer choice.     

Given the following gene sequence showing the coding, non-template strand (bold is promoter), what is the sequence of the transcribed RNA?

Chicken cells normally express c-src, a kinase involved in cell cycle regulation.  The Rous sarcoma virus causes tumor development in chickens by over-expressing v-src, a mutant form of the src kinase, in chicken cells that still produce the normal kinase c-Src.    A.  Based on this information, is v-src is most likely a proto-oncogene, oncogene, or tumor suppressor?  (select one, 2 points)   B.  Explain your selection for part A.  Be specific. (4 points)

Briefly explain one method used by cells to quickly and reversibly convert an enzyme from an active to an inactive state. 

A cross between two salt-tolerant corn plants yields 100 offspring, 78 salt-tolerant and 22 salt-intolerant.    A.    Predict the genotypes of the parent plants. (2 points)   B.    Use the “insert chart” function to add a Punnett square that supports your prediction (3 points).    

In a cancer genomes database, you find multiple mutations in the FOS gene in several types of cancers. Most of these cancer-associated FOS mutations are homozygous, and expression of these mutant versions of FOS in cells with normal FOS genes does not cause them to divide abnormally.  What type of gene is the mutant FOS most likely to be?

Use the image below to answer the following questions. 2 points each. ​ A.  If the bottom strand of the DNA from the diagram above serves as the template strand, the RNA sequence, left to right 5′ to 3′, is: ​ B. If the bottom strand of the DNA serves as the template, the amino acid sequence of the protein produced from the RNA would be: ​
