3 Billion Base Pairs per Cell


7 days

From The Biology of Prenatal Development.Buy Now

Script: Each human cell contains approximately 3 billion base pairs.

The DNA of a single cell contains so much information that if it were represented in printed words, simply listing the first letter of each base would require over 1.5 million pages of text!

If laid end-to-end, the DNA in a single human cell measures 3 1/3 feet or 1 meter.

All ages referenced to fertilization, not last menstrual period.
