Exploring the Structure of DNA and RNA

The video tutorial explains the structure of nucleic acids, focusing on DNA and RNA. It describes the components of DNA, including the phosphate group, nitrogenous bases, and the double helix structure. The video also covers the differences between DNA and RNA, highlighting RNA's single-stranded nature and its role in protein synthesis.
