Well, DNA is not something you can see with the naked eye. However if you could grab a sizable chunk and pick it out with the naked eye it would certainly be a transparent to white color and viscous in nature. This is mainly due to the long chains of polymers and bonds that together make up the macromolecule.
A few interesting facts about DNA:
1. Because of the inherent limitations in the DNA mechanisms, if humans lived long enough, they would eventually develop cancer.
2. Hydrogen peroxide (in concentrated amounts) can damage the DNA structure so badly that it can erase the code structure by unwinding the double helix. But worry not, the concentrations of your household hydrogen peroxide are so minute that won't cause anything other than erasing bacteria around your mouth.
3. DNA occurs as linear Chromosomes in Eukaryotes and circular Chromosomes in Prokaryotes.
4. DNA was fully embraced as the macromolecule of life in 1853 when Watson and Crick suggested the double-helix model in the journal Nature.
