Nucleic Acids: DNA and RNA Structure | Class 11 Biology | New PTB Book 2025 | F.Sc Part 1

Video Description Learn about the fundamental building blocks of life in this lecture on Nucleic Acids, covering the New Syllabus 2025 for F.Sc 1st Year Biology. We break down the complex structure of nucleotides, pentose sugars, and nitrogenous bases according to the National Curriculum of Pakistan. Key Topics Covered: Types of Nucleic Acids: Defining DNA and RNA. Cellular Location: Where to find DNA and RNA in the cell. Nucleotide Composition: Understanding the Nucleoside (Base + Sugar) and Phosphoric Acid. Pentose Sugars: Distinguishing between Ribose and Deoxyribose. Nitrogenous Bases: Detailed explanation of Pyrimidines (Cytosine, Thymine, Uracil) and Purines (Adenine, Guanine). Structural Linkage: How the ester linkage at Carbon-5 forms the sugar-phosphate backbone. This lecture is tailored for students preparing for their exams using the new PTB book.
