Analysis
1.
Compare the DNA between each of the different cells. Is each cell’s WHOLE DNA (not just highlighted part) different
or the same? Explain your thinking.
2.
If you have the same DNA as the other cells, why did your cells make a different part of Jeff’s face?
(CHALLENGE: How do you think the cells do this?)
