RNA

  1. 1. Chapter 13 RNA and Protein Synthesis
  2. 2. DNA vs. RNA  How does RNA differ from DNA? (1) the sugar in RNA is ribose instead of deoxyribose (2) RNA is generally singlestranded and not doublestranded (3) RNA contains uracil in place of thymine
  3. 3. RNA  Think of RNA as a disposable copy of a piece of DNA  Primary job is to make proteins (protein synthesis)
  4. 4. Transcription RNA molecules are produced that are complementary to the DNA sequences in genes  Order of bases complements the base sequence of DNA  In eukaryotes, RNA is made in the nucleus 
