Tumor Suppressor Genes: p53 and Rb | NEET Biology 2026 🧬

"Welcome back to BIO-GURU 🧬 If Oncogenes are the 'gas pedals' that drive cancer, Tumor Suppressor Genes are the essential 'brakes' that keep our cells safe. Today, Bio-Guru breaks down how these genetic heroes prevent tumors and what happens when they fail!" [What’s in this video?] In this NEET-special lecture, we explore the molecular guardians of our genome: The Concept of TSGs: Understanding how these genes inhibit cell division and promote DNA repair. The p53 Protein: Why it is called the 'Guardian of the Genome' and how it triggers apoptosis. The Retinoblastoma (Rb) Gene: How it acts as the gatekeeper of the G1 to S phase transition. Loss of Function: What happens when the cell loses its ability to stop uncontrolled growth. Role of BRCA and APC [Why watch this?] This video is specifically tailored for NEET-UG aspirants, B.Sc. students, and anyone preparing for medical entrance exams. We simplify complex molecular biology into easy-to-remember concepts with Bio-Guru’s signature style! Subscribe for more simplified Medical Biology & Biotech lectures!
