  1. Last Class • Protein • Carbohydrate • Lipid • Nucleic acid

  2. DNA What is it?

  3. DNA • is an abbreviation for Deoxyribonucleic Acid • is the polymeric molecule whose chemical sequence determines individual hereditary characteristics

  4. What makes up DNA?

  5. What makes up DNA? • Phosphates • Deoxyribose sugar • Nitrogen bases

  6. DNA and RNA Structures

  7. Creation of DNA strands Hydrogen Bonding Between Base Pairs (A to T and G to C)

  8. DNA is like a ladder

  9. DNA determines characteristics • The DNA bases (A, T, C, and G) make a code of letters • These letters make “words” which are called genes • These “words” make “sentences” called the genetic code • Our cells “read” these “sentences” and perform special functions
