How many DNA strands are there in humans?
At least 4,600 trillion.
Each diploid cell in the human body consists of 46 strands of DNA, each representing each of the 46 chromosomes in the cell. Since there are about 100 trillion 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. This number, however, does not take into account the millions of bacterial cells that live inside the body, each having about a strand of DNA. So a safe estimate would be at least 4,600 trillion strands of DNA in the human body. http://www.numberof.net/number-of-dna-strands/
