Cell Cycle Regulators & Tumor Suppressor Genes | Proto-oncogenes & Oncogenes

The video tutorial explains the differences between proto-oncogenes and oncogenes, highlighting how oncogenes can lead to cancer. It covers the transcription of DNA to mRNA and the translation into proteins, focusing on cell cycle regulators. The tutorial discusses the cell cycle phases, checkpoints, and the consequences of mutations in cell cycle regulators, leading to uncontrolled cell division and cancer. It also differentiates between proto-oncogenes and oncogenes, and explains the role of tumor suppressor genes and proteins in preventing uncontrolled cell growth.

What are the three major properties of cancer cells?

Describe the process of how a mutation in a proto-oncogene can lead to cancer.

How do tumor suppressor proteins function to prevent cancer?
