7. How to Get Six Feet of DNA into a Six Micron Suitcase
In each nucleus of a human cell, the total length of DNA contained in it is about 6 feet long. Now, the size of a nucleus in a human cell is only 6 microns in width. A micron, otherwise called a micrometer, is 1 one-millionth of a meter. To put...
