These four nucleotides (and their respective nitrogenous bases) are:Ĭytosine and thymine are pyrimidines, a type of six-membered heterocyclic molecules. There are four types of nucleotide molecules depending on the type of nitrogenous base attached. The building blocks of a DNA are molecules called nucleotides, that consists of a deoxyribose sugar (a 5-carbon sugar), a nitrogenous base attached to the sugar, and a phosphate group. Given below is a brief account of the DNA structure as well as the steps through which a DNA molecule makes copies of itself with an extraordinary accuracy. But even more enthralling is its ability to self-replicate and generate another molecule similar to itself. The simple chemical code of the DNA molecule gives rise to the immense complexity of all living organisms. With this foundation, and the research by several scientists like Rosalind Franklin, the structure of this molecule was finally deciphered by James Watson and Francis Crick. It took several interesting experiments by Frederick Griffith, Avery, MacLeod, McCarty, Alfred Hershey, Martha Chase etc., to discover that DNA is the hereditary material. This is equivalent to copying 100 dictionaries (with 1000 pages each) word to word, page to page, and symbol to symbol, with only one mistake!ĭeoxyribonucleic acid or DNA is the fascinating molecule that stores and passes all the necessary information from one generation to another.
