6. Nucleic Acids Molecules containing hydrogen, oxygen, nitrogen, carbon & phosphorus

7. Function in the body Store & transmit hereditary or genetic information

8. Building Blocks Nucleotides – the building blocks of nucleic acids Nucleotides have 3 parts: 5-carbon sugar A phosphate group Sugar and phosphate are held together by strong covalent bonds A nitrogenous (nitrogen-containing) base (adenine, thymine, cytocine, guanine) Bases are held together by weak hydrogen bonds.

9. Check for Understanding #1 The diagram below represents a portion of a nucleic acid molecule. The part indicated by arrow X could be 1 adenine 2 ribose 3 deoxyribose 4 phosphate

10. Nucleic Acids Video

11. Check for Understanding #2 The weakest bonds in a double-stranded molecule of deoxyribonucleic acid exist between the (1) deoxyribose sugars (2) phosphate groups (3) nitrogenous bases (4) 5-carbon sugars

12. Examples Ribonucleic Acid (RNA) Deoxyribonucleic Acid (DNA)

13. Check for Understanding #3 One similarity between DNA and RNA molecules is that they both contain 1 the same sugar 2 genetic codes based on sequences of bases 3 a nitrogenous base known as uracil 4 double-stranded polymers
