In what way does the alpha helix (of some protein) and RNA differ?
Helical structures in RNA is a result of it folding back on itself. The helical structures in the protein is a result of the regular coiling of the alpha helix;
The helical structures in RNA are due to complementary base pairing between different segments of the same strand. The helical structures in protein are due to presence of hydrogen bonds within a single segment of polypeptide.
The sections in RNA are made up of a double helix. The sections in protein are made of a single helix.

Your blog post about RNA is simple and can be easily understand. With RNA-Seq we can know the inner structure and the function of RNA better.
