What is a rna nucleotide?
A nucleotide is a nucleotide letter ‘A’, ‘U’, ‘G’, ‘C’, ‘R’, ‘Y’, ‘N’. These letters are default for XRNA (and what are initially viewed) and will always be known by the program. To change the viewed nucleotide letter to something else (like the lowercase equivalent, or some kind of mutation symbol see the CMB-RNA XRNA faq for annotation.) A viewed nucleotide also implies a possible nucleotide number. This can be a line pointing from a nucleotide to a number or just a line. When editing and refering to a nucleotide a translation of a nucleotide will also translate its nucleotide number.
