Nucleic Acids Explained | DNA Structure, B-DNA vs Z-DNA & Denaturation | Biochemistry

In this video: Quickly master The Molecular Architecture of Nucleic Acids for CSIR-NET & NEET. We break down the chemistry of the "Blueprint of Life": from the components of a nucleotide to the stabilizing forces of the Double Helix (Hydrogen bonds & Base Stacking) and why DNA is the chosen storage molecule over RNA. 🏆 Book 1:1 Strategy Call with AIR 52: Stuck in your prep?
