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:

3.

4.

1.

2.

5.

DNA Basics & Organization

DNA Structure & Function

DNA Replication

RNA Structure & Function

Comparing DNA & RNA

1. DNA Basics & Organization

(Inside) On Top Half of 1 st Flap write:

1. Make the following flow chart:

Cell  Nucleus  Chromosome  DNA  Gene

(Inside) On Bottom Half of 1 st Flap write:

DNA stands for “Deoxyribo nucleic 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 2 nd Flap write:

Directions:

1.

2.

3.

Write “DNA STRUCTURE”

Cut out panel and glue into flap

Circle the following:

• 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 2 nd Flap write:

Directions:

1.

2.

Write “DNA FUNCTION”

Make the following table:

Function: Facts:

Storage of Genetic Code • 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

Passing of Traits • 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 3 rd Flap write:

Directions:

1.

Cut out panel and glue into flap

2.

3.

Color the following in picture #1:

• Green= Parent

Strand

• Yellow=

Complementary

Strand

Outline the following: in picture #2:

• Red = Leading strand

• Blue = Lagging strand

#1

#2

(Inside) On Top Bottom Half of 3 rd Flap write

1.

2.

Write “Steps of DNA Replication”

Make the following flow chart:

Leading Strand ONLY!

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

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 4 th 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 5 th 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:

DNA

RNA
