🧬 Early M Phase Explained |cohesin Rings, Spindle Fibers & Regulation part 1 🔥 | CSIR NET 2026

🧬 Cell Cycle & Regulation: Early M Phase — Cohesin Rings, Spindle Fiber Arrangement and Regulation Welcome to LifeScience Diaries! 🌿📚 What happens when a cell enters the early M phase? How are sister chromatids held together, and how do spindle fibers organize to ensure accurate chromosome segregation? In this lecture, we explore the key molecular events of early mitosis, focusing on cohesin rings, spindle assembly, chromosome organization, and cell cycle regulation. 📚 Topics Covered in This Lecture: ✅ Introduction to early M phase ✅ Chromosome condensation and mitotic entry ✅ Role of cohesin rings in sister chromatid cohesion ✅ Regulation of cohesin during mitosis ✅ Spindle fiber formation and organization ✅ Kinetochore–microtubule attachment ✅ Role of centrosomes and spindle poles ✅ Important mitotic regulatory proteins ✅ Exam-oriented concepts and molecular mechanisms 🎯 Useful for Competitive Examinations: 🔹 CSIR NET Life Sciences 2026 🔹 DBT-BET 🔹 ICMR 🔹 GATE Life Sciences 🔹 SET and other life science examinations 💡 Why watch this lecture? Build a clear understanding of early mitotic events, chromosome behavior, and the molecular machinery responsible for accurate cell division.
