1. Chapter 13
RNA and Protein
Synthesis

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. RNA
 Think
of RNA as a disposable
copy of a piece of DNA
 Primary job is to make proteins
(protein synthesis)

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

