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?

Answer 1

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.
