Chapter 9, Problem 3AQ

The gene encoding the beta subunit of RNA polymerase from Escherichia coli is said to be orthologous to the rpoB gene of Bacillus subtills. What does that mean about the relationship between the two genes? What protein do you suppose the rpoB gene of B. subtilis encodes? The genes for the different sigma factors of E. coli are paralogous. What does that say about the relationship among these genes?

Epstein-Barr virus is associated with Burkitt’s lymphoma. The rate of EBV and c-myc gene translocation seems related, as both are highest in Equatorial Africa, lowest in North America and intermediate in South America. Explain what is c-myc translocation and why it results in overexpression of c-myc. What is the role of EBV in causing c-myc gene overexpression?
A gene contains the sequence CGCATACGGTAC that results in the amino acid sequence arg-ile-arq- tyr. A mutation in this gene has a G inserted after the second C in the strand. How will this mutation affect the phenotype? A)This will affect the phenotype because although most of the protein will be identical, the first amino acid will be different. B)This will not affect the phenotype because only the second amino acid is different from the original protein. C)This will not affect the phenotype because the protein will be identical to the original protein. D)This will affect the phenotype because all of the amino acids after the first one will be different from the original protein.
Consider the phase variation of flagella in Salmonella. Describe the phenotype of a cell in which hin is deleted. Will it be motile? Will it undergo phase variation? Which flagellin(s) will be used, if any? Name two bacterial defenses against bacteriophages and explain how they work How might a phage evolve resistance to the CRISPR host defense?
