y explores the fundamental relationship between DNA, cancer development, and modern therapeutic approaches used to treat cancer. It builds a strong foundation for understanding how genetic changes at the molecular level can lead to disease and how biotechnology is used to fight it.

The lesson begins with an overview of DNA as the genetic blueprint of life, explaining how genetic information is stored, replicated, and expressed within cells. It highlights how mutations or errors in DNA can disrupt normal cellular functions and lead to uncontrolled cell growth.

A key focus is on cancer biology, explaining how normal cells transform into cancer cells due to genetic mutations, environmental factors, or inherited risks. It introduces the basic mechanisms of tumor formation, cell division dysregulation, and metastasis.

The course also covers modern cancer therapies, including chemotherapy, radiotherapy, targeted therapy, and immunotherapy. It explains how medical biotechnology contributes to developing more precise and effective treatments that reduce damage to healthy cells while targeting cancerous ones.

Additionally, the lesson highlights the role of genetic engineering and molecular diagnostics in early cancer detection and personalized medicine.

By the end of this lesson, learners will understand how DNA damage leads to cancer and how biotechnology is revolutionizing cancer treatment strategies for improved patient outcomes.
