In prophase I, the stage that closely resembles prometaphase of mitosis is:
Options
- ADiplotene
- BChaismata
- CLeptotene
- DDiakinesis
Correct answer
D. Diakinesis
Step-by-step solution
The final stage of meiotic prophase I is diakinesis. This is marked by terminalisation of chiasmata. During this phase the chromosomes are fully condensed and the meiotic spindle is assembled to prepare the homologous chromosomes for separation. By the end of diakinesis, the nucleolus disappears and the nuclear envelope also breaks down. Diakinesis represents transition to metaphase.
