Question

What do you predict would happen if the yeast had a mutation that prevented the g protein from binding gtp? what do you predict would happen if the yeast had a mutation that prevented the g protein from binding gtp? no shmoo would form in response to mating factor. phosphorylated fus3 kinase would accumulate in the cell in the presence of mating factor. shmoos would form even in the absence of mating factor. mating factor would be unable to bind to the g protein-coupled receptor?

Answer 1

If yeast had a mutation that prevented the G protein from binding to to the GTP it is not unreasonable to predict that the G protein would bind with another amino acid to form a complete protein for the yeast. It could potentially interfere with yeast's reproduction as well.
