The Discovery of DNA

It is amazing how important things are being discovered by persons who spend most of their lives dedicated to research . It is perhaps more amazing how a scientist discovers one thing while trying to discover other things . Imagine if no one was patient enough to conduct experiments to prove their assumptions . If that was the case , we would not know today that DNA is the genetic material . This will discuss how DNA

was discovered , its structure and the scientists who contributed to the discovery

Deoxyribonucleic acid (DNA ) is considered as the molecular blueprint of life that can be passed to the next generation . It was discovered in 1953 (University of Georgia , 2007 ) from experiments seeking to understand bacterial pneumonia which claimed many lives during the twentieth century . During these experiments , researchers stumbled into discoveries which later on became the reagents for further experiments leading to the discovery of DNA as the genetic material (O 'Connor 2008 . DNA looks like a twisted ladder wherein rungs are secured by two out of four molecules that are interlocking . These molecules are nucleic acid bases . The four molecules include thymine , adenine , cytosine , and guanine (University of Georgia , 2007

Certain scientists have been notable for conducting experiments leading to the discovery of DNA . One of these was Oswald Avery whose team was trying to find out how to treat lobular pneumonia . From his experiments he proved that DNA indeed...
