#Unit 2. Cellular Organization

  1. Unlike DNA, RNAs are unmethylated, and only the four standard bases – A, C, G and U are found in RNAs.

  2. The primary structure of an RNA is the linear sequence of nucleotides.

  3. The secondary structure of an RNA is dominated by hydrogen bonding between bases on the same strand.

  4. Stem-loop structures are common in RNA and consist of complementary sequences that form stable base pairs, separated by a short sequence of unpaired bases.
