1. Introduction to DNA: What it is and Why it Matters
– Brief history of DNA discovery
The discovery of DNA as the genetic material of living organisms is credited to several scientists. In 1869, Friedrich Miescher identified a substance called nuclein, which he found in the nuclei of white blood cells. However, it was not until the early 1900s that the importance of nuclein was recognized. In 1928, Frederick Griffith conducted an experiment that demonstrated the existence of a “transforming principle” in bacteria that could transfer genetic material from one organism to another. In 1944, Oswald Avery, Colin MacLeod, and Maclyn McCarty confirmed that the transforming principle was DNA.
In the 1950s, James Watson and Francis Crick, with the help of Rosalind Franklin and Maurice Wilkins, made a breakthrough in understanding the structure of DNA. They proposed the double-helix model, which showed that DNA consists of two complementary strands that are held together by hydrogen bonds between their base pairs. This discovery opened the door to a deeper understanding of the molecular basis of genetics and led to significant advances in genomics research.
– Chemical structure of DNA
DNA is a long polymer made up of repeating units called nucleotides. Each nucleotide consists of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine (A), guanine (G), cytosine (C), and thymine (T). The sugar and phosphate molecules make up the backbone of the DNA strand, while the nitrogenous bases project inward from the backbone.
