Crick, Watson, and Franklin: The
Race to Discover the Structure of
DNA
-By Cynthia Stokes Brown
1. Read the article
2. Read to each circled number
and answer the question on
the handout in complete
sentences.
3. If there are 3 lines – then 2
complete sentences. If there
are 6 lines – then 5 complete
sentences. If there are 5 lines
– then 4 complete sentences.
Franklin’s X-ray image
Watson & Crick’s DNA model
Essential Question:
What are the
components of DNA.
Let’s build a
DNA
molecule….
DNA Origami
• The bases on the right (from top to bottom) are:
GAGCAGTGTGT.
• The bases on the left (from top to bottom) are:
CCTCGTCACAC
• You need to find the complementary base pair
• Remember to color on the diagonal (as shown below)—only
do half, the other half is the complementary base pair
G
A
T
C
The colors are
not correct, so
use the key on
the previous
slide. But put
the “letters” in
the correct spot,
color the correct
diagonal, and
cut out the
square.
