If unwound and tied together, the strands of DNA in one cell would stretch almost six feet but would be only 50 trillionths of an inch wide. If all the DNA in your body was put end to end, it would reach to the sun and back over 600 times (100 trillion times six feet divided by 92 million miles).
How long is the average unwound human chromosome?
On the average, a single human chromosome consists of DNA Molecule that is almost 5 centimeters.
Length of a Human DNA Molecule.

|Mitchel, Campbell Reece. Biology Concept and Connections. California, 1997.||“At actual size, a human cell’s DNA totals about 3 meters in length.”||3.0 m|
How long would human DNA be stretched out?
If you stretched the DNA in one cell all the way out, it would be about 2m long and all the DNA in all your cells put together would be about twice the diameter of the Solar System.
How long is human DNA in inches?

|The World Book Encyclopedia . Chicago, World Book, 1999.||On the average, a single human chromosome consists of DNA molecule that is about 2 inches long.||2 , 3 m|
How much DNA does a human have?
The diploid human genome is thus composed of 46 DNA molecules of 24 distinct types. Because human chromosomes exist in pairs that are almost identical, only 3 billion nucleotide pairs (the haploid genome) need to be sequenced to gain complete information concerning a representative human genome.
Even bananas surprisingly still share about 60% of the same DNA as humans!
How big is a human DNA strand?
A DNA strand is a long, thin molecule—averaging only about two nanometers (or two billionths of a meter) in width. That is so thin, that a human hair is about 40,000 times as wide.
How much of human DNA is junk?
Our genetic manual holds the instructions for the proteins that make up and power our bodies. But less than 2 percent of our DNA actually codes for them. The rest — 98.5 percent of DNA sequences — is so-called “junk DNA” that scientists long thought useless.
Many of the “housekeeping” genes that are necessary for basic cellular function, such as for replicating DNA, controlling the cell cycle, and helping cells divide are shared between many plants (including bananas) and animals.” … We do in fact share about 50% of our genes with plants – including bananas.”
Which animal DNA is closest to humans?
Ever since researchers sequenced the chimp genome in 2005, they have known that humans share about 99% of our DNA with chimpanzees, making them our closest living relatives.
