Question #45251
The Question
The dictyotene stage of a primary oocyte is functionally analogous to the (quiescent) phase of a somatic cell, as both represent a state of extended cell cycle suspension. Which of the following statements accurately distinguishes or correlates these two physiological states?
Options
- A.
Both states represent a temporary suspension of the cell cycle where the DNA content of the cell is strictly maintained at 2C.
- B.
While a somatic cell enters by exiting the phase, the primary oocyte enters its quiescent state during Prophase-I and requires an LH surge to resume division.
- C.
Cells in both the phase and the dictyotene stage become metabolically inactive to prevent spontaneous and erroneous DNA replication.
- D.
The release of a somatic cell from requires mitogens, whereas the primary oocyte resumes meiosis-I solely under the direct influence of an FSH peak.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Integrating Cell Cycle (DNA content and G0 metabolic state) with Human Reproduction (Oogenesis arrest stages and hormonal triggers).
Students often falsely assume arrested cells are metabolically inactive, confuse the DNA content of arrested oocytes (4C) with G0 cells (2C), and misattribute the resumption of meiosis to FSH instead of the LH surge.
