Ciclo Celular: Interfase - Aula 31 - Módulo I: Biologia Celular | Prof. Gui

🧬 EXTENSIVE BIOLOGY COURSE: https://bit.ly/extensivobio 🚀 MASTERING THE ENEM (Brazilian National High School Exam): https://bit.ly/DoE2026 🎯 PLATFORM: https://bit.ly/plataformaGUI 🟢📣 MATERIAL HERE: https://bit.ly/BIOLOGIAprofGUI In this class, I explain the phases, DNA replication, and the mechanisms that control cell division. I also show how failures in checkpoints can allow uncontrolled cell multiplication and contribute to the development of cancer. This content is frequently tested in the ENEM and university entrance exams, especially in questions involving cell cycle graphs, DNA quantity, chromosomes and chromatids, mutations, cancer, apoptosis, and p53 protein. ⏱️ Chapters 00:00 Cancer and cell cycle disruption 01:11 Cell cycle and interphase 02:37 Interphase time and cell division 04:06 G1, S, and G2 phases 04:50 G1 phase: growth and metabolism 06:04 S phase: DNA replication 07:41 Single and duplicated chromosome 09:16 Centriole duplication 09:48 G2 phase: preparation for division 10:53 Graphical summary of interphase 11:36 G0 phase 12:49 Cell cycle checkpoints 13:50 Apoptosis and DNA damage 15:10 G1/S, G2/M, and metaphase/anaphase checkpoints 15:30 p53 protein, cyclins, and CDKs 17:07 Message Final Lesson If this lesson helped you, please like, subscribe to the channel, and share it with anyone else studying Biology for the ENEM and university entrance exams. #CellCycle #Interphase #Biology
