Gene Expression and Regulation

Framing Question

How do genes and genomes control changes in an organism's structure and function throughout its life cycle?

Learning Objectives

  • Describe how differential histone modification modulates gene activity and is utilized in developmental progression .
  • Use a model systems to describe investigations of evo-devo.
  • Describe genetic cascades; use the sex-determination cascade to explain how differential gene expression can result in the development of different sexes.
  • Explain how polarity is established in a developing embryo using gene expression gradients.
