Question
Name a cell that is found arrested in diplotene stage for months and years. Comment in 2-3 lines how it completes cell cycle?
Solution
In oocytes of some vertebrates, diplotene can last for months or years.
- Lampbrush chromosomes or diplotene chromosomes are found in the diplotene stage of most animal oocytes of frog or amphibians.
- Lampbrush chromosomes are observed in the meiotic prophase. These chromosomes become normal after growth and thus complete the cell cycle.
