Why do chromosomes condense during prophase So that kinetoch
     Why do chromosomes condense during prophase?  So that kinetochore proteins will attach to them.  So that they will not be damaged when they are moved around the cell.  So we can them  So that sister chromatids will stay together.  All of these are TRUE. 
  
  Solution
The correct option is :
All of these are TRUE.
Prophase is a stage of Mitosis when the chromatin condenses into two rod-shaped structures called chromosomes in which the chromatin becomes visible. This process is known as chromatin condensation. Since the genetic material has been replicated in the prior interphase of the cell cycle, there are two identical copies of each chromosome in the cell. Those copies are called sister chromatids. One kinetochore is assembled on each of the two sister chromatids of a chromosome, and both sister kinetochores become attached to opposite spindle poles by metaphase. Chromosomes condense before mitosis to allow them the ability to move smoothly, without becoming entangled and breaking.
