Textbook Question
Chapter 20, Problem 11P
Two different protein complexes called SCF and APC covalently add a small polypeptide called ubiquitin to cyclin proteins. The addition of ubiquitin to a protein targets that protein to be degraded by another protein complex called the proteasome. The SCF complex is activated during S phase, and the APC complex is activated during M phase.
| a. | To which cyclins (A, B, D, or E in Fig. 20.14) do you think SCF couples ubiquitin? What about the APC? |
| b. | How might cells activate SCF and APC only at the correct times? |

Please help me to draw this by hand. In as much detail as possible, hand draw a schematic diagram of the hypothalamic-pituitary-gonad (HPG) axis in the human female. Be sure to include all the relevant structures and hormones. You must define all abbreviations the first time you use them. Please include (and explain) the feedback loops.

Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE. 1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site 4. BMP4 on outside-> nodal Are all of these occuring opposite to AVE?arrow_forward

What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forward
