DNA Foldable
Directions:
• Fold 3 pieces of paper, so you have 5
layered flaps
• Write “DNA” on the top flap as a title
On each flap write:
1.
2.
3.
4.
5.
DNA Basics & Organization
DNA Structure & Function
DNA Replication
RNA Structure & Function
Comparing DNA & RNA
1. DNA Basics & Organization
(Inside) On Top Half of 1st Flap write:
1. Make the following flow chart:
Cell  Nucleus  Chromosome DNA  Gene
Segment
2. Glue in the following picture below
it of DNA
(Inside) On Bottom Half of 1st Flap write:
DNA stands for “Deoxyribonucleic acid”
(type of organic molecule)
DNA is the instructions for making proteins
that carry out life functions
2. DNA Structure &
Function
(Inside) On Top Half of 2nd Flap write:
Directions:
2.
Write “DNA STRUCTURE”
Cut out panel and glue
into flap
3.
Circle the following:
1.
•
•
•
•
•
Green= Phospahte Group
Red= Sugar
Blue=Nitrogenous bases
Yellow=Nucleotide
Purple= Sugar-Phosphate
backbone
DNA is has a double helical shape!
(Inside) On Top Bottom Half of 2nd Flap write:
Directions:
1.
2.
Write “DNA FUNCTION”
Make the following table:
Function:
Facts:
Storage of Genetic Code
•
Passing of Traits
•
double stranded sugar-phosphate backbone
• internal code (nitrogenous bases are
protected by sugar-phosphate backbone)
• coiled tightly to allow for more surface area
 meaning more room to store genetic code
nitrogen bases are complementary (A or
adenine always bonds with T or thymine; C or
cytosine always bonds with G or guanine)
• weak hydrogen bonds hold bases togetherallow for ease during replication
3. DNA Replication
(Inside) On Top Half of 3rd Flap write:
Directions:
1.
Cut out panel and glue
into flap
2.
Color the following in
picture #1:
•
•
Green= Parent
Strand
Yellow=
Complementary
Strand
Outline the following:
in picture #2:
3.
•
•
#1
Red = Leading
strand
Blue = Lagging
strand
#2
(Inside) On Top Bottom Half of 3rd Flap write
1.
2.
Write “Steps of DNA Replication”
Make the following flow chart:
1. DNA unwinds
with help of
protein helicase,
this breaks
weak hydrogen
bonds between
bases
2. The protein
primase attached to
the parent strand,
this helps bind
(attach) new
nucleotides
Leading Strand ONLY!
3. Elongation DNA
protein polymerase
reads template
strand and
continuously adds
new nucleotides that
are complementary
to the parent strand
Lagging Strand ONLY!
5. DNA
Termination
6. DNA repairs itself
4. DNA
primers are
removed &
DNA ligase
adds sugars
and
phosphates in
gaps made by
fragments
3. DNA primase
adds more primers,
DNA is elongated in
short segments
(okazzki fragments)
by DNA polymerase
and then is
4. RNA Structure &
Function
(Inside) On Top Half of 4th Flap write:
Directions:
1.
2.
Write “RNA STRUCTURE”
Cut out pictures, glue into flap and label types of RNA
mRNA
tRNA
rRNA
(Inside) On Top Bottom Half of 4th Flap write:
Directions:
1.
2.
Write “RNA FUNCTION”
Make the following table:
Type of RNA:
Function:
mRNA
“messenger”
•
rRNA
“ribosomal”
•
tRNA
“transfer”
•
makes a copy of DNA in the nucleus
• travels from nucleus  cytoplasm 
ribosome
• bases in mRNA are read in sets of 3 =
codon
“home” of protein synthesis= mRNA brings
code, tRNA brings amino acids and rRNA puts
the two together to make protein
gathers amino acids
• travels to the ribosome
• contains a set of 3 bases in tRNA
(anticodon)
5. Comparing DNA & RNA
(Inside) On Top Half of 5th Flap write:
Directions:
1.
Cut out panel and glue
into flap
(Inside) On Bottom Half of 5th Flap:
Directions:
 1. Draw & Complete the following Venn
Diagram:
