Welcome to Lesson 4 of the Human Biology Masterclass.
In this lesson, we explore DNA — the molecule that stores the genetic information needed to build and maintain the human body.
You'll learn:
• The structure of DNA and how the four bases — A, T, G, and C — store biological information
• The difference between genes, the genome, and non-coding DNA
• How DNA replication copies billions of base pairs before cell division
• How genetic information flows from DNA to RNA to protein
• What mutations are and how substitutions, insertions, deletions, and duplications can affect the body
• How cells detect and repair different types of DNA damage
• Why failures in DNA repair can contribute to cancer and genetic disease
From the double helix to gene expression and DNA repair, this lesson introduces the molecular mechanisms that allow genetic information to be stored, copied, interpreted, and protected.
Understanding DNA is essential for understanding genetics, development, disease, evolution, and many aspects of human health.
