The DNA molecule has 2 long backbones of phosphates and sugars with bases sticking out are running right next to each other. Then the back bones coil so it will fit into the nucleus. Because the DNA coils is because it contains millions if atoms, DNA has to coil.
If you took all the DNA from your cells and uncoiled it, it would stretch out to a total length of about 2 meters. This compact packaging allows the DNA to fit inside the nucleus of a cell while still containing all the genetic information needed for an organism.

Human Dna in Diploid -Somatic- Cells has the extended Length of 1.87 meters. Sperm and Egg Cells -Gametes- are Haploid Cells, with one half of The Genetic Complement, so the length is 0.935 meters [repeat - in length - jammed into a Space about three microns across].
DNA strands are packed into structures called chromosomes. Chromosomes are made up of long strands of DNA that are tightly coiled and condensed to fit inside the nucleus of a cell.
The nucleus contains thin strands of DNA known as chromatin. Chromatin is made up of DNA and proteins, and it packages the DNA to fit inside the nucleus of a cell.

Single molecules of DNA are long and stringy. Each cell of your body contains six feet of DNA, but it's only one-millionth of an inch wide. To fit all of this DNA into your cells, it needs to be packed efficiently. To solve this problem, DNA twists tightly and clumps together inside cells. Even when you extract DNA from cells, it still clumps together, though not as much as it would inside the cell.

Jupiter can fit
DNA of eukaryotic cell is present in nucleus.
The DNA is coiled round and packed very tight so it can fit inside something as small as a nucleus.

the DNA tightly coils around a group of bead like proteins called histones
The total length of DNA is so long that it cannot possibly fit inside a nucleus in its unfolded state. So DNA is folded and coiled around Histones for more compaction.
DNA strands are packed into structures called chromosomes. Chromosomes are made up of long strands of DNA that are tightly coiled and condensed to fit inside the nucleus of a cell.
Loose or uncoiled chromosomes are actually DNA in the form of chromatin. Chromatin is a complex of DNA and proteins that helps organize and condense the DNA into a structure that can fit inside the cell's nucleus.
