Station 5:
In one sentence, answer the question
below.

before the cell divides to make a two
new cells?
1
____________________
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?
A cell replicates its DNA before it divides so that
the two new cells EACH get a full set of DNA.
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?
1
______________________
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 living things have the A, T, C, G bases
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!)
1
______________________
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!)
It is “double” because there are two sides to the
DNA. It is a “helix” because of its spiral shape.
Station 8:
Fill in the blanks below.
The two strands of DNA are said to be
1
________________
(opposites/complementary).
2 (two
words) rule.
This is true because of the ____
_______
Station 8:
Fill in the blanks below.
The two strands of DNA are said to be

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?
1
______________________________
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?
OLD NEW OLD NEW
DNA replication is semi-conservative because at the end of replication, one
of the strands is from the original DNA and one is the newly made strand.
