Concept

Problem: Explain how the structure of a chromosome change as a cell moves from interphase to mitosis?  What phase(s) has/have highly condensed DNA? Why is it important that this phase or phases have highly condensed DNA?What phase or phases have less condensed DNA? Why is it important that this phase or phases have less condensed DNA?

FREE Expert Solution

Metaphase is the phase of mitosis where chromosomes the in the highest form. This facilitates easier alignment at the metaphase plate. This also prevents other chromosomes from interfering one another as less condensed chromosomes has thin thread like structure that can tangle with one another. More condensed form is also noted in anaphase as this allows tangle-free migration of chromosomes to opposite poles during anaphase.
