How many nucleotides are in your bodies?

Answer 1

The [haploid] human genome contains about 3 x 10E9 nucleotide pairs and that's just in one cell, so we are looking at an extremely large number when you take into consideration all of the cells in your body. That doesn't include the nucleotides that are part of the RNA/protein synthesis apparatus, which comprise another formidable quantity in each cell. I'm just guessing now, but I would say it would have to be in the 10E15 - 10E20 range.

Answer 2

The human body contains trillions of cells, and each cell contains a complete set of DNA. The human genome is made up of approximately 3 billion nucleotides.
