In the G0 phase the cell is metabolically active
cdc-25 is a phosphatase and it is involved in the last step of formation of active MPF. For G1 to S transition cyclin -E is required.

Explanation of Correct Statements
The correct statements regarding cell cycle regulation and protein interactions are:
1. cdc-25 is a phosphatase which helps in formation of active MPF.
- cdc-25 plays a crucial role in activating the Maturation-Promoting Factor (MPF) by dephosphorylating specific sites on cyclin-dependent kinase (CDK).
- This activation is essential for the cell to progress from G2 phase to M phase (mitosis), thus facilitating cell division.
2. Cyclin-E required for G1 to S transition.
- Cyclin E is critical for the progression from the G1 phase to the S phase of the cell cycle.
- It forms a complex with CDK2, which helps in the initiation of DNA replication, signaling the cell to enter the S phase.
3. In G0 phase cell is not metabolically active.
- The G0 phase is a quiescent state where cells are in a resting phase and do not actively divide.
- However, it is important to note that cells in G0 can still perform basic metabolic functions, though they are not preparing for division.
4. The concentration of cyclin-D is high in G1 phase.
- Cyclin D is indeed prevalent during the G1 phase and is essential for the progression of the cell cycle by activating CDK4 and CDK6.
- This activation allows the cell to move past the restriction point, leading to DNA synthesis.
Conclusion
Among the listed statements, A, B, and D are correct. Statement C, while it describes a phase of the cell cycle, inaccurately portrays the metabolic activity of cells in G0. Cells in G0 can be metabolically active, albeit not in a state of division.
