Visualize this, almost all the cells in your body have a nucleus. The nucleus contains your DNA which is the blueprint to your physical and mental self. Everything you are physically, mentally, and on a molecular level is stored in this DNA. Considering the complexity of our bodies as well as the accumulated excess DNA from evolution, the DNA should be a hefty set of molecules! True to that, if extended to its full length, the human DNA comes out to be six feet long. That is two meters worth of nucleotide rope, condensed and stored in each cell of your body at the nanoscale once such cell consisting of this DNA is the Neutrophil. 

Neutrophils are a part of the immune system. Their job is to protect us against pathogens such as bacteria. They do this through various methods such as phagocytosis (cell eating), degranulation, and NETosis. 

NETosis is a form of cell death where instead of quietly imploding, the cell releases all of its content, including the extended DNA, out of its body and into the spaces between the other cells in your body. This net-like DNA physically stops the movement of the bacteria by catching them and thus makes the chances of the bacteria spreading through your body low. These half-dead neutrophils continue to float around sites of injury and neutralizing the threats to our bodies in a zombie-like state.

The wonders of the human body never cease to amaze!
