Cell Differentiation

Genes are expressed or not expressed in response to internal or environmental factors, and this plays a role in cell differentiation.

Use your notes and the article to answer the following questions:

Remember to use CER

What is epigenetics?

How does gene expression lead to cell differentiation and cell specialization?

What role do environmental factors play in cell differentiation?

Explain how the analogy of the genome as a library helps describe the process of gene expression in cell specialization.

Describe how drugs that alter gene expression can both positively and negatively influence cell differentiation.
