Answer to Question #103113 in Cell Biology for Nadine M

Question

In meiosis, what is the purpose of the nuclear membrane and why does it disintegrate? Also, are the centrioles and spindle fibers shown in all steps of meiosis?

Answer 1

Meiosis is a type of cell division that sexually reproducing organisms use to produce gametes.

Meiosis involves several steps to name: Prophase, Metaphase, anaphase and telophase.

Nuclear membrane refers to an envelope that encloses the nucleus and it disintegrates at the end of prophase I to allow meiotic spindle to enter the nucleus.

Centrioles an spindle fibers are shown in all the steps of meiosis from the beginning where centrioles align themselves at the opposite ends and as division proceed they move in all possible directions
