How many strands of DNA is in a human?

Answer 1

If you use the average of 75 trillion cells for an adult human body and assumed DNA present in every cell, at an average of 6 ft in length, you would come up with the following:

DNA in ft=450 trillion

DNA in mi=85.2 billion

Answer 2

Humans typically have 23 pairs of chromosomes in their cells, each contributing one strand of DNA. Therefore, humans have a total of 46 strands of DNA in their cells.

Answer 3

An adult human contains around 100,000,000,000,000 cells, each cell has 46 chromosomes so that would yield 4,600,000,000,000,000 strands but there is DNA in mitochondria too!

Answer 4

There are 12 strands of DNA in a human body

Answer 5

They have about 46 in each nucleus. A person with more or less is likely to be mentally challenged.
