DNA Damage & Repair 🧬: Molecular Biology • Types • Biochemistry • MBBS • Dr. Rajesh Tanwar


DNA har cell ka genetic blueprint hota hai, lekin UV radiation, ionizing radiation, chemicals aur free radicals ki wajah se DNA damage ho sakta hai. Agar DNA damage repair na ho to mutations, genetic disorders aur cancer develop ho sakte hain.

Is lecture mein hum DNA Damage ke types (Depurination, Deamination, Thymine Dimers, Single & Double Strand Breaks) aur DNA Repair Mechanisms (Direct Repair, Base Excision Repair, Nucleotide Excision Repair, Mismatch Repair aur Double-Strand Break Repair) ko simple aur exam-oriented way mein discuss karenge. MBBS 1st year students ke liye yeh topic molecular biology ka foundation hai aur university exams, NEET PG aur FMGE ke liye bahut important hai.
