DNA is threadlike, but it's packaged into chromatin when the cell is operating normally and chromosomes when the cell is dividing.
During G1 and G2 DNA is in the form of nucleosomes - or 10nm fibre.
The most tightly-coiled form of DNA is a chromosome.
When cells are not actively dividing, the DNA just looks like grainy blobs.
DNA is found in the nucleus of eukaryotes or in the cytoplasm of prokaryotes. The DNA forms complex strands known as chromatin, and when dividing, chromosomes.
DNA is threadlike, but it's packaged into chromatin when the cell is operating normally and chromosomes when the cell is dividing.
It's called euchromatin, and is attached to histones.
Chromosomes are structures in the nucleus of the cell which contain DNA and can best be seen when the cell is dividing.
When DNA is packed up tightly in dividing cells, it is referred to as a chromosome. The packing process is called DNA condensation.
During G1 and G2 DNA is in the form of nucleosomes - or 10nm fibre.
It is condensed into chromosomes.
When the cell isn't dividing, DNA is found in chromosomes within the nucleus. During this phase, which is called interphase, DNA is called chromatin but isn't visible, even under a microscope.

Interphase is considered non-dividing, but that doesn't mean that the cell's organelles and DNA aren't replicating.
Meiosis.
