7. Station 5: In one sentence, answer the question below
Station 5: In one sentence, answer the question below. Why does the DNA of a cell replicate before the cell divides to make a two new cells? ____________________
DNA is copied before the cell divides to ensure that all new cells in the body have the same instructions for building the body.

8. Station 6: Answer the question below in 1 sentence
Station 6: Answer the question below in 1 sentence. All living things have DNA, but not all living things have the same DNA. Knowing this, what does the DNA of all living things have in common? ______________________
All DNA in every organism is composed of the same four nitrogenous bases (A T C G)

Station 7: Answer the question below in 2 sentences. Why is the shape of DNA described as a double helix? (There are two reasons you should describe. Think about the two words!) ______________________
Double = 2, Helix = Twisted Ladder/Spiral Staircase shape

10. Station 8: Fill in the blanks below.

The DNA consist of ½ original (old) and ½ complementary (new) strands.

14. Station 12: Read the information and answer the question
Station 12: Read the information and answer the question. When you mix oil and water in a cup, they do not mix. When you mix food coloring and water in a cup, they do mix. This means that oil does not dissolve in water. What type of biomolecule is oil? __________________
Lipid

15. Station 13: Which of the following did Miss Rosalind Franklin help to discover? - The function of DNA - How DNA was created - The structure of DNA ___________________ 1

16. Station 14: Fill in the blanks in the paragraph
Station 14: Fill in the blanks in the paragraph. Use the following words: antiparallel, double helix, complementary
DNA is in the shape of a double helix. The two sides, or strands, of DNA are complementary to one another. The direction of the DNA strands are said to be antiparallel because they run in opposite directions, allowing the bases to bond in the middle with the backbone on the outside.
