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?
Each new cell needs an
____________________
exact copy of the DNA in its
nucleus.
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?
The DNA
of all living things is made of the
______________________
same parts – phosphate, deoxyribose, and
four nitrogen bases (A-T, C-G).
Station 7:

a double helix?
(Think about what those words mean!)
A DNA
molecule is made of two
______________________

Station 11:
Look at the diagram below and focus on the last
picture on the right. In one sentence, what does
it mean that DNA replication is semiconservative?

______________________________
original
and one new strand.
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

double ______.
helix The
DNA is in the shape of a ______
two sides, or strands, of DNA are complementary
___________
to one another. The direction of the DNA strands
