What Does DNA Stand For? | Tutorial | Latest Technology News

Ever since testing became a central piece of evidence in the OJ Simpson trial, these three letters have become one most well-known acronyms in the English language. But what does  for?

What Does DNA Stand For?

DNA is 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 other acid is ribonucleic acid (RNA).

What Is DNA?

Simply stated, deoxyribonucleic acid is the genetic code of a living thing. Every living creature 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 AncestryDNA have found commercial uses for your DNA information including DNA testing and DNA artwork.

DNA is a very tiny molecule that’s shaped like a double helix. Two biopolymer strands coil around each other creating the double helix shape. The sequence that runs along this double helix is what makes up our genetic information.

DNA: How Do You Pronounce 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: De-oxy-rib-on-u-cleic

DNA In Pop Culture

DNA references are abundant in pop culture now. In Jurassic Park, scientists used DNA from a prehistoric mosquito trapped in amber to recreate dinosaurs. In the CSI TV series, forensic investigation teams use DNA to help solve crimes.

But until 1995, most people 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, 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, they can also get credit for DNA. In 1869, Swiss physician Johann Friedrich Miescher was the first scientist to discover something that he called “nuclein”. It’s a rather disgusting discovery story. Miescher found nuclein while examing the old pus from surgical bandages. But Miescher wasn’t exactly sure what 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 heredity and the famous DNA double-helix model we all know today. All of this DNA research culminated in 1990 when the world’s largest collaborative biological project, The Human Genome Project, began. The international scientific research project successfully mapped over 3 billion nucleotides contained in the human genome. If only Miescher knew how much would become from his simple examination of pus.
