3 Billion Base Pairs per Cell


7 days

From The Biology of Prenatal Development.Buy Now

Script: Varje mänsklig cell innehåller ungefär tre miljarder sådana baspar.

En enda cells DNA innehåller så mycket information att om det skulle motsvaras av skrivna ord, skulle bara den första bokstaven i varje bas kräva mer än 1,5 miljoner sidor text!

Om de lades på rad, skulle DNA:n i en enda mänsklig cell räcka 3 1/3 fot eller 1 meter.

All ages referenced to fertilization, not last menstrual period.
