When the GATA-1 gene is on the cell will produce hemoglobin (an oxygen carrying protein).
Checkered pattern
The GATA-1 gene is being expressed a lot!

On your Gene Expression Chart, put three check marks in the ON column for the GATA-1 gene.
On your cell model, draw three petal shaped figures within the cell. Each should extend from one margin of the cell to the other.
Your cell is now a red blood cell (erythrocyte). Look at the chart below to follow your path of development.
Red Blood Cells
Red Blood Cells
Red blood cells (RBCs), also called erythrocytes, are the most common type of blood cell. RBCs take up oxygen in the lungs, or gills of fish, and release it into tissues throughout the body. In humans, mature RBCs are oval disks that lack a cell nucleus and most organelles to maximize space for hemoglobin, an iron-rich molecule that binds oxygen and is responsible for the red color of the cells and the blood. Nearly half of the blood's volume is made up of red blood cells.
