Question

During ________ the chromosomes, which were distinct and condensed, begin to spread out into a tangle of chromatin. a nuclear envelope re-forms around each cluster if chromosomes. the spindle begins to break apart.

Answer 1

During telophase in mitosis or meiosis II, where chromosomes which were previously distinct and condensed, de-condense and spread out into a tangle of chromatin. At the same time, the nuclear envelope re-forms around each cluster of chromosomes in each of the daughter cells, and spindle fibres disintegrate.

Chromosomes are unlikely to de-condense and spread out into a tangle of chromatin during telophase I (i.e. Telophase of Meiosis I), since Meiosis is still ongoing, and the genetic material should be in its condensed form during Meiosis II as well. 

Hope this helps! :)

Answer 2

Answer: " Prophase" Chromatin condenses into chromosomes, and spindles begin to form.
