🎓 WUnderstanding the structure of DNA and RNA is fundamental to biology.
In this video, we explore what makes DNA the genetic material of living organisms and how its unique structure allows it to store, copy, and transmit genetic information.

📌 Topics covered in this lecture:

What properties a genetic molecule must have

Why DNA (not protein) is the genetic material

Structure of nucleotides:

Nitrogenous bases

Pentose sugar (ribose & deoxyribose)

Phosphate group

Difference between nucleotide and nucleoside

At which carbon the base and phosphate attach to sugar

Phosphodiester bond and 3′–5′ linkage

DNA double helix and complementary base pairing (A–T, C–G)

Difference between DNA and RNA

Role of ATP (AMP, ADP, ATP) as an energy carrier

Importance of DNA replication and protein synthesis

🧬 Clear diagrams are explained slide-by-slide to help students visualize complex concepts easily.

🎓 This lecture is ideal for:

FSC / ICS / Intermediate Biology

O Level & A Level Biology

BS / Undergraduate Life Sciences students

MDCAT aspirants
