In which phase of cell division is oocyte arrested?
Correct answer: C. Prophase I
- A. Interphase
- B. Anaphase II
- C. Prophase I
- D. Both prophase I and II
Explanation
The correct answer is:c) Prophase IProphase I is the first phase of meiosis and is characterized by the pairing of homologous chromosomes in a process called synapsis. This phase includes the formation of genetic crossovers between homologous chromosomes, increasing genetic diversity. The oocyte is arrested in this phase for a long period of time, often for years or even decades, depending on the species and the individual. And for the 2nd time it is arrested at metaphase-II.
