Question

Lampbrush chromosomes are observed in
  1. Meiotic prophase
  2. Meiotic metaphase
  3. Mitotic metaphase
  4. Mitotic prophase

A
Mitotic metaphase
B
Mitotic prophase
C
Meiotic prophase
D
Meiotic metaphase
Solution
Verified by Toppr

The correct option is D Meiotic prophase
  • Lampbrush chromosomes are known as diplotene chromosomes because they are formed during the diplotene stage of prophase1 of meiosis cell division due to the active transcription of many genes.
  • They are a special type of chromosome found in the developing oocytes of most animals (except mammals).
  • So, the correct answer is 'Meiotic prophase'.
