Describe the proteins produced when cells of Escherichia coli experience a heat shock. Of what value are they to the cell?
Answer to relevant QuestionsExplain how alternative sigma factors control sporulation in Bacillus. Most biosynthetic operons need only be under negative control for effective regulation, whereas most catabolic operons need to be under both negative and positive control. Why? Promoters from Escherichia coli under positive control are not close matches to the promoter consensus sequence for E. coli. Why? Why can it be said that the retrovirus genome is unique in all of biology? The promoters on genes encoding early proteins in viruses like T4 have a different sequence than the promoters on genes encoding late proteins in the same virus. Explain how this benefits the virus.
