If you stretched the DNA found in one of your cells from end to end, it would extend approximately 2 meters or 6.5 feet. Every single cell in your body can pack away this much DNA by winding it around proteins called histones. The DNA is opened and closed when cells need access for normal processes such as cell division. However, many cancer cells are extra sensitive to the packing and unpacking of DNA because they divide much faster than our healthy normal cells. Understanding which proteins specifically pack and unpack DNA could help us to target these cancer cells with inhibitors more accurately.
