Your DNA Could Stretch To Pluto And Back Over 17 Times

Samuel Reason | February 15th, 2018

The human genome, the genetic code that makes a human well a human is a fascinating science. It continues to open up new doors and understanding about our wellbeing and health. Some things today we still do not fully understand. But what we do know is that the length of all your DNA combined is so long, it could reach Pluto and back over 17 times.

How in the world is that possible you ask? The human cell contains over 23 DNA molecules. And each one of them contains up to two and a half million nucleotide pairs. Nucleotides are the building blocks that come together to create you. But they also are sort of like the architect plan of your body: they store all your genetic information.

Now a nucleotide comes in pairs and averages about five centimeters long, though some can be as big as 8. That does not really sound like they are very big though, right? But there are over 37 trillion cells in the human body. This means if you were able to unravel it all, then those little nucleotides would form a line so long that it could easily go from the Sun to Pluto and back.

Pretty incredible to think that they all fit inside the human body. And that is not the only fact that makes DNA such a fascinating science subject. Scientists are researching to make vaccines for deadly viruses such as HIV, flu or hepatitis C from synthetic DNA. The “fake” DNA can teach the body how to create the cells and proteins it needs to allow your immune system to fight these viruses. You can basically look at it like sending your DNA to university to learn some new skills.

For example, DNA vaccines for melanoma and hemorrhagic diseases have already been developed for horses and dogs. So it does seem only a matter of time before scientists can produce the same benefits for ourselves. And with so much more DNA to unravel it looks like scientists will discover new perceptions from DNA research for years to come.
