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: DNA RNA
