Briefly describe how transcription, phosphorylation, protein-protein interactions and proteasome-mediated turnover are involved in cell cycle regulation (like G1,S,G2,M Phases).

I understand that phosphorylation is related to to cyclin dependent kinases (CDKs), but unsure about the rest. Is the proteasome part related to ubiqutin in some way?

Different cyclin-dependent protein kinases (CDKs) regulate the transition of eukaryotic cells from one phase of the cell cycle to another: from G1 to S, S to M, or M to G1. Describe the different mechanisms by which the enzyme activity of the CDKs is regulated over time during the cell cycle and how such mechanisms are altered in different cancers. In some cells such as trophoblasts (cells of the placenta) and megakaryocytes (precursors to blood platelets), cells will undergo repeated rounds of G1 and S phase without G2 or M phases รขย€ย“ what is the advantage of this cell cycle for such cells?
