What type of cells are these?

• A Cells

• B Cells

• T Cells

• Seriously?

Cells differentiate to perform different functions because

• all genes are turned on inside that cell

• all genes are turned off inside that cell

• different genes are turned on inside that cell

• different genes are turned on or off inside that cell

During the process of differentiation

• all sections of DNA are activated to determine the structure of a body cell

• ONLY ONE section of DNA are deactivated to determine the structure of a body cell

• only specific sections of DNA sequence are activated to determine the structure and functions of a body cell

• different DNA

• deactivated DNA

• gene expression in specific parts of DNA
