PLEASE 1. Review the DNA article and interactive in the lesson.

DNA—deoxyribonucleic acid—we all have it in every cell of our bodies. DNA is similar to a fingerprint—everybody's DNA is different. (The only exception is identical twins. They have the same exact DNA.) Scientists and investigators count on DNA analysis for its accuracy. This unique genetic code can be found in all body cells, including hair, skin, and blood.

2. Write a paragraph of at least five complete sentences that answers the following questions:
What are the advantages and disadvantages of each medium used for the DNA information?
Why can it be helpful to present ideas in more than one medium?
Which medium did you like better and why?
Which medium do you feel taught you the information better and why?
How do your answers compare with those of your classmates based on the poll results?
