Structure of DNA: The Double Helix
Introduction:
DNA stands for DeoxyriboNucleic Acid. It is a type of Nucleic Acid, which has deoxyribose sugar in it instead of ribose. DNA has a double helical structure. By double helix, the meaning is two strands of polynucleotide running parallel and coiled around each other through hydrogen bonding. DNA is hereditary material in all the living organisms on this planet. The basic mystery behind its heredity nature resides in the same double helical structure. The double helix enables it to get replicated in a semiconservative manner. The one strand acts as a template to form another strand around it and the process goes on. The discovery of this double helical structure proved to be a milestone in the history of physical biology. The structure has enabled the scientists to understand many crucial functions in cells.
This term paper explains the structure of DNA through its historical manifestations and importance in the heredity.
Nucleic Acids:
Nucleic acids are organic chemicals found in living cells and have vital functions to carry out in there. Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA) are two forms of nucleic acids (Ts 'o, 2012). There are some definite differences between the two forms. The first difference is in the type of sugar. The sugar in RNA is common ribose but in DNA one oxygen atom is removed from the 2’of ribose (Chargaff, 2012). Both DNA and RNA are known for their functions in heredity and development of…
