How long would DNA be stretched out?

Answer 1

You have about 10 trillion cells in your body, so if you stretched the DNA in all the cells out, end to end, they'd stretch over 744 million miles. The moon is only about 250,000 miles away, so all your DNA would stretch to the moon and back alomst 1500 times. The sun is 93,000,000 miles away, so your DNA would reach there and back about 4 times!

Answer 2

It would 6 feet long or 2 meters

If completely unraveled, human DNA would stretch from the Earth to the Moon.

If you stretch it and not unravel it, the distance is on average about 6 ft. (2 m) long, but is a very thin thread.

The single human chromosome on average consists of DNA molecules approximately 2 inches long.

The Physics Factbook [see link below] gives the formula of:

"The length is (length of 1 bp)(number of bp per cell) which is (0.34 nm)(6 × 109)"

Answer 3

Surprisingly, despite the cell being so small that you can't see it with the naked eye, and therefore the nucleus (where the DNA is stored) is even smaller than that, complete DNA strands, if unwound and uncoiled would measure 2 meters!! that's over 6 feet long

Answer 4

A common citation for the length of DNA in our bodies is that one cell of DNA contains about 5 - 6 feet (2 meters) of DNA per cell. Estimates place the number of cells in our body at about 100 trillion in total. Not all of those cells contain DNA (blood cells do not, for example) so we can lower that number to perhaps 50 - 70 trillion DNA containing cells.

Let's take the lower estimate. 50 trillion x 6 ft = 300 trillion ft, or about 60 billion miles. Since the moon is 260,000 miles from us, then 60 billion / 260,000 = 218,000. In short, the DNA in one human body would stretch to the moon and back 109,000 times (at least).

Answer 5

DNA is a spiral coiled thread in the nucleus of every living cell. There are about 10 trillion cells in your body and if stretched out they'd reach over 744 million miles.

Answer 6

If you were to stretch out a single strand of DNA, it would be about 2 meters long. This is because DNA is tightly coiled and packaged into chromosomes within the cell nucleus.

Answer 7

6,000 miles to the moon

Answer 8

about six feet
