- 21U RNA expression variant
Variations in the biogenesis or stability of the 21U-RNA class of molecules compared to control. Molecules are classified as 21U-RNA based on the presence of a 5'U and a conserved upstream motif, which may specify the production of these molecules, in addition these molecules are typically 21nt in length.
- miRNA expression variant
Variations in the biogenesis or stability of the microRNA class of molecules compared to control. In C. elegans these molecules are endogenous single-stranded regulatory molecules, 19-25 nucleotides long, with the potential to arise from hairpin, foldback, structures from their primary transcripts.
- siRNA expression variant
Variations in the biogenesis and stability of the small interfering class of RNA molecules compared to control. In C. elegans these molecules are antisense to mRNA's and may be processed from long double-stranded RNA.
- endo siRNA production variant
Animals exhibit variations in the length or amount of any endogenous small interfering RNA molecule populations compared to control.
