Number of DNA in Humans

How many DNA are there in humans?

About 4,600 trillion strands.

Each diploid cell in the human body has 46 strands of DNA, each representing each of the 46 chromosomes in the cell. Since there are about 100 trilion cells in the body (American Association for the Advancement of Science estimate), in which majority are diploid, this means that there are about 4,600 trillion DNA strands in the body.
