The Main Principles of Heredity: The Chemical Structure of DNA

The video tutorial explains the structure of DNA, focusing on its double helix form composed of two polymeric strands. It delves into the arrangement of nucleotides, highlighting their anti-parallel nature. The tutorial also covers the major structural components of DNA, such as the deoxyribose sugar backbone and nitrogenous bases, which are crucial for genetic information. The video further explains the types of nitrogenous bases, purines and pyrimidines, and the base pairing rules that form the genetic code.
