"WebThe last phase of mitosis is called telophase. It follows the preceding anaphase without transition. The kinetochore fibres break down, the nuclear envelope is rebuilt and the chromosomes decondense. After the decondensation is completed, the genes can be read off again and the nucleus has its working form again. " - In what phase do chromosomes decondense
