L-01 NUCLEIC ACID -1 |CSIR NET LIFESCIENCES |

In this lecture, we begin the Nucleic Acids series with a complete discussion of DNA structure and fundamentals. This session builds the conceptual base required for CSIR NET, GATE, BARC, DBT, and other life science exams. We will cover: • What are nucleic acids • Components of DNA – nitrogenous bases, sugar, phosphate • Nucleoside vs nucleotide • Phosphodiester bond • Directionality of DNA (5′ → 3′) • Chargaff’s rule • Watson and Crick model of DNA • Types of DNA forms (A, B, Z DNA) • Important conceptual points for competitive exams This lecture focuses on clarity of concepts so that you can solve MCQs, assertion–reason, and analytical questions confidently. If you are preparing for CSIR NET Life Sciences, make sure you understand this chapter deeply because DNA structure forms the foundation for replication, transcription, mutation, and molecular biology as a whole. Stay consistent. Master the basics. The advanced topics become much easier after that. #CSIRNET #GATE #BARC #DBT #LifeSciences #NucleicAcid #DNA #MolecularBiology _______________________________________________________________________________ 📞 Call us on: 9258915003, 9548592602, 7905655626 🌐 Visit on: https://cpaprep.in/ Telegram Link: https://t.me/bioniila Instagram:   / cpaprep_lif.  .
