The alcohol used causes the precipitate to form due to a reaction allowing the hydrogen bonds between the nucleotides to form, which causes the DNA to become efficient packed and twisted together.
DNA can be spooled out on a glass rod because of its long length.
The bodies that carry genetic information are rod shaped, not red. These bodies are referred to as DNA, which is deoxyribonucleic acid.
DNA ans histones proteins coil to form rod shaped structures called chromosomes.
Chromosomes are rod-shaped structures made of coiled DNA and proteins. They carry genetic information and are found in the nucleus of most living cells.
Chromosomes are the rod-shaped specimens found in the nucleus. They are the hereditary material called DNA. They form when a single DNA molecule and its associated proteins coil tightly before cell division.
If heated to a hundred degrees, chromosomal DNA would denature. Meaning the it would come apart and the complementary DNA strands would separate. One way to get DNA to spool (around a glass rod for example) is to remove it from the cell and precipitate it in solution. This can be done with with help of sodium chloride and isoamyl alcohol.
Native DNA precipitates as fibers when alcohol is added to a solution containing DNA. The DNA fibers can then be spooled onto a glass rod.

No, DNA is not soluble in ethanol. When the 2 are mixed, DNA can be spooled out by stirring the solution with a glass rod.

The two-rod structures that contain the cell's DNA is the chromosome.
