user3553: I prefer proteins, but I occasionally dabble with DNA as all biologists need to do from time to time. On this SE I noticed that there are tags for rna, dna, and mrna.
Inspired by an inconclusive tagging enzymes as proteins meta question, I'm wondering if it would be much more efficient to just use the nucleic acid tag rather than these specific tags? I guess I am asking people working in DNA or RNA, are there situations where the other nucleic acid is a completely different kettle of fish?
Example
This came up specifically after I noticed this question which requires specific expertise on RNA and DNA, but also generally would use the nucleic acid tag. That's three tags for as far as I can see could all be under one supertag since now there is no room for a biochemistry tag for example.

user6: RNA and DNA can have very different functions. They're similar molecules, but are generally used for completely different purposes. The tag nucleic-acids  is far too broad, even the dna and rna tags still have useful potential subdivisions like ribozymes or rna-interference or dna-quadruplexes. 
The actual issue is that the rna and dna tags are overused. Not every question that involves RNA somewhere needs to be tagged this way. We also don't tag every question that involves a protein with the protein tag. 
A question about transcription doesn't need an rna tag, it probably should have a genetics tag and a transcription tag, but while RNA is involved in transcription, that doesn't mean it should be tagged this way.
