snRNA | [3] | ||
Comment: Dihydrouridine is reported in a total enzymatic digest of nuclear 5S RNA from rat [3]. However, this sole report of D in snRNA was not verified by sequencing of the RNA because pD could not be distinguished from pU [3]. | |||
chromosomal RNA | [4] | ||
Comment: This RNA is reported as a chromatin-associated 3.2-3.8S species, with an unusual concentration of dihydropyrimidine nucleosides, but its occurrence as a separate class of RNA remains controversial. For review, see [5]. |
