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
