DID YOU KNOW? * DNA stands for deoxyribonucleic acid, and it is the hereditary material in humans and virtually all other organisms. The information that DNA carries is stored as a “code” that is made of four different chemicals— adenine (A), guanine (G), cytosine (C), and thymine (T). The sequence of these bases dictates how that organism is made. DNA bases pair up, with A pairing with T and G pairing with C. A sugar molecule and a phosphate molecule also attach to each base to create a nucleotide, and these nucleotides are then arranged into the DNA double helix.
* There are more than 3.2 billion bases (or letters) in human DNA. Published as a book with standard-sized font, human DNA would contain just four letters …AGCTTGCAGGGG… and so on, for over 1.5 million pages. * Uncoiled and unraveled, the DNA in just one of your cells would be more than 6 feet long. All of your body’s DNA, stretched end to end, would extend more than 10 billion miles, from here to Pluto and back.
* The human genome encodes for nearly 21,000 total genes, about 1,800 more than worms, 12,000 fewer than corn, and 25,000 fewer than rice or wheat. A bewildering 98% of the human genome is not dedicated to genes, but to enormous stretches of DNA that are interspersed between or within genes. Scientist have yet to fully understand what this “junk DNA” does or does not do. — NutriCellix - 1 minute ago
