What is the function of DNA from day to day? **– The function of DNA from day to day is to direct the functioning within the cells of your body.** 3. Describe how long strands of double-helical DNA fit into the nucleus of a single cheek cell. – **Long strands of double-helical DNA fit into the nucleus of a single cheek cell, the double helix is packaged and wrapped around proteins, folded back onto itself and coiled into a compact chromosome.** 4. What was the purpose of using the cell lysis solution? – **The purpose of using the cell lysis solution is so the DNA can be freed.** 5. Why does the DNA become visible once the alcohol is added? **– DNA becomes visible when the alcohol is added because; DNA is soluble in water, but much less soluble in alcohol.**

7. Why is DNA referred to as your genetic fingerprint? – **DNA is referred as your genetic fingerprint,** **everyone’s DNA is different. No one has the same DNA.** 8.

=Diaper Dissection:=

Our group cut the diaper in half. Brandon and I tested a whole half of a diaper. Whereas Elissa and Brooke dissected each layer at a time. While Brandon and I were dissecting, at first we slowly dumped 40 ml on the diaper. It held perfectly so we did that 2 more times. Each time no water leaked. Afterwards, we dumped 50 ml on the diaper slowly. It also didn't leak so we dumped 50 ml on 3 more times. After the 3rd time of doing it water started to leak out of the bottom of the diaper. After 250 ml the diaper no longer absorbs water at the top of the diaper it rolls down the diaper to the bottom. The more water in the diaper, the harder it gets for the water to absorb expanding. The diaper held 320 ml total.
