The total length of the human genome is over 3 billion base pairs. The genome is organized into 22 paired chromosomes, plus the X chromosome (one in males, two in females) and, in males only, one Y chromosome. These are all large linear DNA molecules contained within the cell nucleus.
First off, the human genome contains 3 billion basepairs divided into 23 chromosomes. A single strand of DNA 3 billion basepairs long would be about 1.02 meters (over three feet) long, which, in humans, is divided into 23 separate pieces (chromosomes) averaging 4.5 cm, each (I guess that's where the 5 cm came from?).irst off, the human genome contains 3 billion basepairs divided into 23 chromosomes.
