Incredible facts
DNA is our body's blueprint, and we wouldn't exist without it. It is a molecule that contains the genetic instruction for development and continues to function in every living organism.
DNA is in every cell in our body, telling it what proteins to produce. We inherit the DNA in our cells from our parents, which is why we share many similarities.
It has the shape of a double helix, like a huge spiral staircase, and each step on this ladder consists of a pair of nucleotides. Errors sometimes occur when DNA is copied, and these errors are known as mutations.

Here are some interesting facts about DNA that can help you understand yourself better.
DNA molecule
1. Bdelloid rotifers are microscopic animals that have been exclusively female for 80 million years. They reproduce by borrowing DNA from other animals.
2. If you had to type one word per second for eight hours a day, it would take 50 years to print the human genome.
3. Instead of venom, braconid wasps inject their victims with a virus that suppresses the immune system and allows the parasitic wasp larva to grow inside the victim. Scientists have found that this virus is unlike any other virus on Earth. It is over 100 million years old and appears to have fused with wasp DNA.
4. If you suddenly undergo a bone marrow transplant, your blood will contain the donor's DNA, which has led to false arrests in the past.
5. Siblings share 50% of their genes, as do parents with children.
6. DNA is damaged about 1 million times a day in every cell in our body. Fortunately, our body has a complex recovery system. If this were not the case, it would lead to cancer or cell death.
7. When it comes to invertebrates, earthworms are our closest relatives. We share more DNA than cockroaches and even octopuses.
8. According to scientists, four families in Iceland have DNA found only in Native Americans. Evidence suggests that Vikings brought a Native American woman back to Europe about 1,000 years ago.
9. The International Space Station has a hard drive called the “immortality disk”. It contains DNA from people like Lance Armstrong and Stephen Hawking in the event of a global catastrophe.
10. Brooke Greenberg, a girl who looked like a child all her life, died at the age of 20. Scientists believe her DNA could be the key to biological immortality.

Human DNA
11. About 8 percent of our DNA is made up of ancient viruses that once infected humans.
12. According to DNA research, Polynesians visited Chile in the 1300s and overtook Columbus to set foot on American soil nearly 200 years earlier.
13. About 2 grams of DNA could hold all the world's digitally stored information.
14. Scientists recorded a song from the Disney cartoon (“It's A Small World After All”) in the DNA of a bacterium that is resistant to radioactivity so that people in the future or other forms in the event of a nuclear disaster lives were able to find it.
15. Zambian doctor John Schneeberger was accused of sexual assault. He implanted a tube containing another person's blood, and when his blood was taken for DNA, he was able to deceive specialists. In the end, he was apprehended.
16. Humans' DNA is 99.9 percent the same. The differences are the last 0.1 percent.
17. The genetic content of an egg can be replaced by a man's DNA and then fertilized with a sperm cell. Thus, two men can become parents to a child.
18. The DNA in all your cells can stretch 16 billion kilometers if you spin it up. That's roughly the distance from Earth to Pluto and back.
19. While there are sites that offer genetic saliva tests that confirm your ancestry, scientists warn that this is a kind of “genetic astrology” and should not be taken seriously.
20. 50 percent of your DNA is similar to banana DNA.
21. Scientists have determined that DNA has a half-life of 521 years, and in 1.5 million years even DNA preserved at its best will be unreadable.
22. Due to the destruction of DNA, it is unlikely that we will ever be able to clone dinosaurs or other prehistoric animals.
23. German police once took DNA samples during a jewelry robbery. The samples pointed to twins Hassan and Abbas O. Both denied involvement in the crime, despite police knowing that one of them had committed the crime.
They were unable to determine which of them did it, as the DNA was almost identical, and under German law, suspects could not be held indefinitely. Thus, the police had no choice but to release the suspects.
24. All people of non-African descent have traces of Neanderthal DNA.
25. During the Hornslet Deep Burial Project by Danish artist Christian von Hornslet in 2013, a time capsule was lowered into the deepest part of the ocean. The capsule contained blood, hair and DNA samples from animals. The goal of the project was to preserve DNA so that extinct species could be brought back to life in the future.
