Identify which of the following statements is a lie?
Select one:
a. Yeasts use paracrine signaling to communicate information on mating with other yeast cells.
b. Yeasts are single-celled eukaryotes; therefore, they have a nucleus and organelles characteristic of more complex life forms.
c. Yeast can reproduce sexually through a signaling pathway known as the mating factor pathway.
Explain a mechanism for how a nuclear-encoded protein is targeted to the inner membrane of the mitochondrion. Explain the mechanism for how a nuclear-encoded protein is targeted to the thylakoid membrane.
Describe an experiment that could be conducted to show that there is a targeting system for a nuclear encoded protein that ultimately finds its way to a specific organelle.

Upon ligand treatment, the cell increased the expression of gene α and decreased expression of gene β. When you inhibit cyclic AMP production by treating the cell with an inhibitor of Adenylyl cyclase, the increased expression of gene α was not observed but the decrease gene β expression was still observed. a) What you can expect for gene α regulation by this ligand? What signaling mechanism could be used? b) To determine how gene β is regulated by the ligand via what signaling mechanism, provide your hypothesis and indicate a potential experiment that you can perform to test that.arrow_forward
