In addition, fixed cytogenetic differences include a centromeric shift, heterochromatic differences on autosomal pairs 16, and the number of nucleolar organizer regions.
Noncoding regulatory RNAs - RNAs that are not translated into protein - include the small nuclear RNAs (snRNAs), the small nucleolar RNAs (snoRNAs), the XIST RNA that mediates mammalian X-chromosome silencing, microRNAs, riboswitches, and the RNA component of the enzyme telomerase.

Δbud23; and mutants affected in early, nucleolar steps in ribosome biogenesis, such as
These modifications are catalyzed by small nucleolar ribonucleoparticles (snoRNPs) through specific base-paring between their RNA component (snoRNA) with the surrounding of the position to be modified.
These pre-rRNA processing defects are consistent with the nucleolar accumulation observed with the D-A2 probe by FISH, and resembles the molecular phenotypes observed upon depletion of Nhp2p or Utp15p: Utp15p was proposed to be required for optimal rRNA synthesis
There is a strong nucleolar signal in restrictive conditions for Ins7/9 and Ins15 consistent with defects in early processing steps.
