7. How to Get Six Feet of DNA into a Six Micron Suitcase

Dr. DNA Dan - A Genetics & Genomics Podcast

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 this in perspective, the average human hair is about 100 micrometers in diameter, and a grain of salt is 500 micrometers in width, give or take.

So how are 6 feet of DNA packed inside such a tiny space? Find out with DNA Dan.
