I'm not sure that non-canonical tRNA bases are modified forms of A,C,G,U (like a methylated A), as opposed to just other bases. Anyone know any chemistry?

Info from the gene article to be incorporated "RNA genes are much harder to locate in genome sequences than conventional genes are. Because cells do not translate them, they lack the distinctive ATG codon that heads all protein-coding sequences and guides bioinformatics searches (more at reading frame)."

sorry to nitpick, but i'm editing a biology paper for publication and was wondering whether its "noncoding" or "non-coding"? according to dictionary.com, noncoding is a word so it seems the former is the case. also, there exists "noncodingdna.com". if there are no objections, i or (someone else) will move this page to "noncoding RNA" in a few days.

My experience is that both "non-coding RNA" and "noncoding RNA" are used about as often. For example, Google searches for each term in NCBI's site (to eliminate popular press): non-coding vs. noncoding. Personally, I think "noncoding" sounds ungrammatical (now _I'm_ being pedantic), but clearly people are using it. As long as one term redirects to the other, I won't complain.

snRNA is not a synonym for non-coding RNA

snRNA (small nuclear RNA) is a class of non-coding RNAs, such as transfer RNA is also a class. But not all non-coding RNAs are snRNAs. Thus snRNA is not a synonym for non-coding RNA --User:AAM | Talk 11:54, 30 March 2006 (UTC)[reply]

Prokaryotic or Eukaryotic

I have a question: Of the 6 rRNAs listed (2 mitochondrial and 4 cytoplasmic) which are specific to prokaryotes?

What is a "RNA gene"?

Is the statement, "Nuclear genome contains c.a. 3000 RNA genes (less than 10% of total gene number)." true?

According to the FANTOM project, only 17,594 of the 33,409 transcriptional units were determined to have coding potential. As a result, all remaining units have the potential to be puative ncRNAs [Okazaki et al. (2002) Nature 420:563-573; Suzuki and Hayashizaki (2004) Bioessays 26:833-843]. A very recent estimate suggests that there may be at least 28,000 ncRNAs within the FANTOM library [Liu et al. (2006) PLoS Genet 2:529-536]. Another estimate has put the percentage, at least in humans, at around 98% [Mattick (2001) Embo Rep 2:986-991].

What exactly are you defining as an "RNA gene" in this statement?

A gene encoding for RNA (obviously). Might also encode for protein in theory; IONO whether such RNA genes have been found (or been looked for). Dysmorodrepanis 00:28, 24 February 2007 (UTC)[reply]
