In intermediate phase of cell cycle, DNA replication occurs (in S-phase), so in inter phase, DNA become unfolded and in relaxed state and is available for replicating machinery.
When cell enter into prophase, DNA folds, coils and super coils and finally become in condensed form, which can be seen by microscope.
So this compact form of DNA is called as chromosome.
Ummm..... I'm not sure who you are but you can put this: My teacher should know that I work best in groups. The teacher can also give me respect, like I would to her.
