What Does DNA Stand For?
DNA isÂ the abbreviation for deoxyribonucleic acid. There are two different nucleic acids that make up the different strands of DNA. Deoxyribonucleic acid (DNA) is the main acid. The otherÂ acid is ribonucleic acid (RNA).
What Is DNA?
Simply stated, deoxyribonucleic acid is the genetic code of a living thing. Every living creatureÂ has their own unique DNA and no one except for an identical twin will have the same DNA as you. Creative companies like 23andMe, DNA11, and AncestryDNAÂ have found commercial uses for your DNA information including DNA testing and DNA artwork.
DNA isÂ a very tiny molecule that’s shaped like a double helix. Two biopolymer strands coil around each otherÂ creatingÂ the double helix shape.Â The sequence that runs along this double helix is what makes up our genetic information.
DNA: How Do You PronounceÂ It?
What does DNA stand for: Deoxyribonucleic acid. It’s is a mouthful. That’s why it’s more commonly known as just DNA. To pronounce “deoxyribonucleic acid”, break it down into shorter pieces:Â De-oxy-rib-on-u-cleic
DNAÂ In Pop Culture
DNAÂ references are abundant in pop culture now. In Jurassic Park, scientists used DNA from aÂ prehistoric mosquito trapped in amber to recreate dinosaurs. In the CSI TV series, forensic investigation teams use DNA to help solve crimes.
ButÂ until 1995, most peopleÂ had never ever heard of DNA. It wasn’t until the murder trial of OJ Simpson that the concept of DNA was introduced to both jurors and the American public. Back then, it was a tough concept to grasp. But today,Â not only do most people believe that the science was valid, they expect it to solve most mysteries.
Who Discovered DNA?
In addition to giving the world Velcro, the Helvetica Font, Swiss Army Knives, and LSD,Â they can alsoÂ get credit for DNA. InÂ 1869, Swiss physician JohannÂ Friedrich Miescher was the first scientist to discover something that he called “nuclein”. It’s a rather disgusting discovery story. MiescherÂ found nuclein while examing the old pusÂ from surgical bandages. But Miescher wasn’t exactly sure whatÂ nuclein was.
It wasn’t until 1881 when a German biochemist named Albrecht Kossel identified nuclein as a nucleic acid. Kossel gave nuclein a proper chemical name, deoxyribonucleic acid. Over the next century, many other scientists made additional discoveries about DNA including its link to heredityÂ and the famous DNA double-helix model we all know today.Â All of this DNA research culminated in 1990 when the worldâ€™s largest collaborative biological project, The Human Genome Project, began. The internationalÂ scientific researchÂ project successfully mapped over 3 billionÂ nucleotidesÂ contained inÂ the humanÂ genome. If onlyÂ Miescher knew how much would become fromÂ his simple examination of pus.
