2. DNA vs. RNA
ïź 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
ïź Think
of RNA as a disposable
copy of a piece of DNA
ïź Primary job is to make proteins
(protein synthesis)
4. Transcription
RNA molecules are produced that are
complementary to the DNA
sequences in genes
ïź Order of bases complements the
base sequence of DNA
ïź In eukaryotes, RNA is made in the
nucleus
