What hypothesis was being tested with the formin strain?
What hypothesis was being tested with the formin strain?
| Formin is required for the signal transduction pathway leading to shmoo formation. |
| Mating factor is required to start the signal transduction pathway leading to shmoo formation. |
| Phosphorylation of formin is required for the signal transduction pathway leading to shmoo formation. |
| Formin causes shmoo formation in mating yeast. |
Solution
Ans: The hypothesis being tested with the formin strain is Formin is required for the signal transduction pathway leading to shmoo formation.
Explanation: The process of Signal transduction occurs in five simple steps:
1. Firstly, Mating factor activates corresponding receptor.
2. Binding of G protein to GTP (Guanosine triphosphate) and thereby becomes activated.
3. Activation of Fus3 by Phosphorylation cascade mechanism, which then moves to plasma membrane.
4. Formin is activated and phosphorylated by Fus3.
5. This activation of formin stimulates the initiation and growth of microfilaments that form the shmoo projections.
