Question

Which component of a eukaryotic cell breaks down at the start of replication and reforms at the end of

Answer 1

Answer:

a.the nuclear membrane

Explanation:

During the late stage of prophase, the nucleolus becomes dispersed in the nucleus and the nuclear membrane breaks down and disappears. This allows the chromosomes to be suspended well in the cytoplasm and get attached to the spindle apparatus.

In telophase, anew nuclear membrane forms around each set of chromatids. So two daughter nuclei are now formed. Each daughter nucleus ends up with the same diploid number of chromosomes as the parent cell. A nucleolus develops in the nucleus of each daughter cell.
