0:24 – Types of Nucleic Acids (DNA vs RNA Explained)
1:10 – Nucleotide Structure | Sugar, Phosphate, Base
2:15 – Nucleoside vs Nucleotide Difference
2:55 – Ribose vs Deoxyribose Sugar | DNA vs RNA Sugar
3:30 – History of Nucleic Acids Discovery (Miescher to Watson & Crick)
4:50 – Nitrogenous Bases | Purines & Pyrimidines
7:20 – DNA vs RNA | Thymine vs Uracil
9:50 – Nucleoside Phosphates (NMP, NDP, NTP with Examples)

What you will learn in this video:
What are nucleic acids and why they are important for life
Types of nucleic acids: DNA (Deoxyribonucleic Acid) & RNA (Ribonucleic Acid)
Structure of nucleotides – sugar, phosphate group, and nitrogenous base
Difference between nucleoside and nucleotide
Ribose vs Deoxyribose sugar – key differences for DNA & RNA
Historical discoveries: Miescher, Kossel, Altmann, Watson & Crick
Nitrogenous bases: Purines (Adenine, Guanine) & Pyrimidines (Cytosine, Thymine, Uracil)
Bonding of bases and how they hold DNA and RNA chains together
DNA vs RNA – role of Thymine in DNA and Uracil in RNA
Formation of nucleic acid polymers from nucleotides

This video is perfect for exam revision and for building a clear understanding of the basics of DNA and RNA structure and function.
