RNA-induced silencing complex (RISC/RITS) remodeling complexes to chromatin to form heterochromatin in telomeres.

The siRNA complex promotes methylation of histone H3K9 by the Clr4 methyltransferase (also known as KMT1, a homolog of Drosophila Su[Var]3–9). H3K9 methylation recruits the S. pombe homolog of HP1, Swi6.

Genetic diversity: It refers to the variety of genes contained within species of plants, animals and micro-organisms. If a species has more genetic variation, it can adapt better to the changed environmental conditions.

C is by far the most common base (41%) and G is the least common base (14%) in rut sites, vary in length.  As a general rule, the efficiency of a rut site increases with the length of the C-rich/G-poor region.

U11 base pairs with the 5’ splice sites; U12 base pairs with the branch point sequence near the 3’ splice site; and U4atac and U6atac provide analogous functions during the spliceosome assembly and activation of the spliceosome. 

U5 is same component in all splicing complexes
