Question

To build up food reserves in the cytoplasm, chromosomes become unfolded to start transcription of mRNA and RNA, during which phase of meiosis ?

Answer 1

In diplotene stage of meiosis I, the chromosomes may unfold to nearly form and start transcription of mRNA and rRNA to build up food reserves in the cytoplasm. This process is most pronounced in the primary oocytes of amphibians, reptiles and birds. In some species, the chromosomes enlarge greatly, assuming lampbrush form.
