DNA: The Nucleic Acid of Life
Discovery in the Nucleus
WEB DNA was originally named a nucleic acid due to its initial discovery within the nucleus, the central compartment of a cell. However, subsequent research revealed that DNA's presence is not exclusive to the nucleus.
Structural Differences between DNA and mRNA
Base Composition
One key difference between DNA and its derivative, messenger RNA (mRNA), lies in their base composition. While DNA contains the nitrogenous bases adenine, cytosine, guanine, and thymine (A-C-G-T), mRNA replaces thymine (T) with uracil (U).
Sugar Molecule
Another contrasting feature is the sugar molecule that makes up the backbone of each molecule. DNA utilizes deoxyribose sugar, while mRNA employs ribose sugar.
