Unformatted text preview: (i.e. green fluorescent protein) transcriptional fusion d) none of the above e) all of the above 3. Bacterial heterocyst formation is considered a development process because… a) heterocysts carry out different functions than the vegetative cells b) heterocysts have a different cellular structure than vegetative cells c) heterocysts have a different function and structure than vegetative cells 4. Do you predict cell to cell signaling to occur between a developing heterocyst cells and vegetative cells and why? 5. In a screen for genes that affect heterocyst formation by Anabena, you isolate a plasmid that encodes the Anabena gene, hetR. This plasmid, when present in multiple copies in Anabena, results in increased heterocyst development after shift to growth medium lacking a nitrogen source. (i.e. A strain with the plasmid develops 4 heterocysts per 10 cells, and a strain with out the plasmid develops 1 heterocyst per 10 cells.) A) What can you conclude regarding the function of hetR in Ana...
