What is Dark DNA?
Dark DNA is an informal term for genetic material that cannot be clarified by scientists. Dark DNA refers to genetic material produced by microorganisms that cannot be classified. Most of Dark DNA comes from ancient transposable and repetitive elements that have low complexity, genetics that are not categorized in the human body and other organisms. Until now scientists and research teams compared genes and proteins using sequence similarity index entries.
Thanks to technology that can sequence DNA sequences that are very long, scientists are now able to solve questions about extinct animals and animals that have successfully evolved in ancient times that are still alive.

In a recent study, scientists discovered the fact that desert mice are very susceptible to type 2 diabetes. That is because of the loss of the Pdx1 gene responsible for producing insulin in these desert mice. But why the desert rat is still able to survive, the researchers found the fact that the Pdx1 gene that is in the body of the desert rat was not completely lost, but they do not yet know why the Pdx1 gene can be vague.
So What Causes DNA to Change?
DNA will continue to change because it goes through a process of mutation. Because DNA is a molecule that has dynamic properties and is very easy to adapt. Therefore the nucleotide sequence that exists in DNA can change as a result of the phenomenon that scientists commonly call mutations. But sometimes a mutation can affect physiological changes in an organism that is affected.

Human and mouse DNA contain about 3 billion pairs of chemical letters or bases. More than 90% of DNA is a non-coding genome, commonly referred to as Dark DNA or junk DNA whose function or function is unknown.
So What are the Ingredients in Our DNA?
DNA has 4 base blocks namely, Adenine, Cytosine, Guanin and Thymine. DNA has a very long molecule that contains a unique genetic code that distinguishes 1 human from another human. and 1 animal with other animals.
The Following are Interesting Facts About DNA that You Should Know About:
- DNA was first discovered by a scientist named Friedrich Miescher in 1869. At that time scientists did not understand DNA as a genetic material in cells, until 1943.
- Humans and cabbage have a DNA similarity of 40 to 50%.
- Scientists at the University of Cambridge discovered the facts and were very sure that humans had similarities or similarities with the DNA of mudworms. That way, we have more in common with mudworms than with spiders, octopus and cockroaches.
- DNA is a very fragile molecule, in one day Dark DNA / DNA will experience 1,000 mistakes wrong caused by errors during transcription, exposure to ultraviolet light and your daily activities. Despite the damage, there will be many mechanisms to repair it, but not all can be repaired. That’s what brings you to mutations, some mutations may not cause damage and instead help your body adapt. But some mutations will cause diseases such as cancer. But do not you worry, because now there is technology that can edit the genome, namely CRISPR.
- It takes 40 years or even more to type the composition of the human genome.
- Humans have a 98% similarity with DNA possessed by chimpanzees.
- Children and parents have almost 100% DNA similarity.
- DNA has a molecule about 600 times the distance from the earth to the sun.
- You and your neighbors have 99% similarity in DNA.
That’s the information we managed to get about Dark DNA and interesting facts about DNA that you should know about. I hope this article can help you get the information you need. Thank you for visiting my site. Don’t forget to share, because sharing is caring.
