DNA was discovered by Friedrich Miescher in 1869, In 1940s Oswald Avery realized DNA contains humans’ genetic blueprint. DNA’s double-helix structure was discovered in 1953 by James Watson and Francis Crick. A helical weird thing occurred to both in a dream before starting their research.
In the human genome there are three billion base pairs of DNA. There are 4 letters for DNA code adenine (A) with thymine (T), and cytosine (C) with guanine (G).
If uncoiled, all the DNA from a single human cell would be about 2-3 metres long. Together, all of the cells in your body contain 10 billion miles of coiled DNA , a return trip to Pluto!
Typing at 60 words per minute for eight hours a day, it would take about 50 years to finish. DNA code for a human can be placed in 1000 books or 263.000 pages from them only 500 are unique to each human.
DNA testing in criminal cases still have a risk that a sibling or even a total stranger could be wrongly convicted.
In 2008, DNA from several notable humans was sent into space on a memory stick stored at the International Space Station. It includes DNA from physicist Stephen Hawking, comedian Stephen Colbert, and Lance Armstrong.
DNA itself is the best storage drive. One can store 700 terabytes of data on a single gram of DNA.
Humans share 98% of our DNA with chimpanzees, we also share 70% with slugs and 50% with bananas. We carry 2% DNA from Neanderthals.
