When the DNA molecule folds, coils and super coils to fit in the cell what structure does it form?

A. Chromosomes

B. Gene

C. Double helix

D. Single helix

Explanation:

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.

In humans. there are total 46 chromosomes.

d. groundwater flows through the subsoil and deposits minerals.
