Differences between DNA and RNA: 1. Uracil, is used in place of thymine and Ribose instead of 2'-deoxyribose. 2. RNA is much shorter than DNA (recall that 1 DNA molecule spans the length of the entire chromosome. RNA may span a few thousand bases of DNA. 3. With a few exceptions ( a few viruses) RNA occurs in single stranded form. The nitrogenous bases can form intra-strand hydrogen bonds with complementary base pairs ( Fig. 4 ). This is important in forming the secondary

Unformatted text preview: structure of RNA where stem/loop or hairpin structures form because the chains fold back on themselves, creating loops and small base-paired stretches between complementary regions. One of the most remarkable and unexpected discoveries of recent years is that some folded RNAs have nucleolytic activity. The RNA enzymes, called ribozymes are able to cleave specific phosphodiester bonds in a manner analogous to protein enzymes....
