2 Nucleic Acids

3 Nucleic Acids DNA (Deoxy-ribo Nucleic Acid) RNA (Ribo Nucleic Acid)

4 Nucleic Acids DNA contains the coded recipes for all the proteins that determine your traits. (Traits are heritable characteristics, like eye color)

5 Nucleic Acids RNA copies the information from DNA and builds the proteins. (Traits are heritable characteristics, like eye color)

25 Nucleic Acid Structure
Sugar Phosphate A G T C T Sugar Phosphate C A G Circle a nucleotide. What kind of bond joins the complementary bases? What makes up the backbones

26 1. What is the material in each cell that contains a set of instructions that control all genetic traits? 2. Where in a cell is DNA usually found? 3. What are the "building blocks" that make up a nucleic acid? 4. What are the three components of a nucleotide? 5. What are the two components of the backbones? 6. To which component of the backbone are the bases attached? 7. What are the four bases? 8. Which bases go together? 9. What type of bond holds the two strands together? 10. What is the twisted shape of the DNA molecule called?

Takes 4 steps: Sugar Phosphate A Phosphate Sugar T A Sugar Phosphate Sugar C Phosphate Phosphate Sugar Phosphate G Sugar C G Sugar Sugar Phosphate C Phosphate Sugar G Phosphate Phosphate Sugar Sugar Sugar Phosphate T Phosphate Phosphate A Phosphate Sugar Sugar G Sugar C T Sugar Phosphate Phosphate

31 Nucleic Acid REPLICATION
1. Unwind (DNA straightens out) Sugar Phosphate A Phosphate Sugar C Sugar Phosphate G T Sugar Phosphate C A G Sugar Phosphate C Phosphate Sugar G Sugar Phosphate A G T C Sugar Phosphate T A Phosphate Sugar T Sugar Phosphate

32 Nucleic Acid REPLICATION
Sugar Phosphate 1. Unwind (DNA straightens out) 2. Unzip (the two strands separate, exposing bases) Sugar Phosphate G Sugar Phosphate A G C T A Phosphate Sugar Sugar Phosphate A Phosphate Sugar G T Sugar Phosphate C A G Sugar Phosphate C Phosphate Sugar C Sugar Phosphate T

33 Nucleic Acid REPLICATION
1. Unwind (DNA straightens out) 2. Unzip (the two strands separate, exposing bases) 3. Complement (free nucleotids match up with bases on strands) T Sugar Phosphate Sugar Phosphate A Phosphate Sugar C T Sugar Phosphate C A G Sugar Phosphate G A Phosphate Sugar Sugar Phosphate A G T C Sugar Phosphate T Phosphate Sugar G Sugar Phosphate C

34 Nucleic Acid REPLICATION
1. Unwind (DNA straightens out) 2. Unzip (the two strands separate, exposing bases) 3. Complement (free nucleotids match up with bases on strands) 4. Bond (the new strands of nucleotides bond together) T Sugar Phosphate Sugar Phosphate A Phosphate Sugar C T Sugar Phosphate C A G Sugar Phosphate G A Phosphate Sugar Sugar Phosphate A G T C Sugar Phosphate T Phosphate Sugar G Sugar Phosphate C
