The oxoG adduct is highly mutagenic because it can base-pair with adenine as well as with cytosine. If it base-pairs with adenine during replication, it gives rise to a G:C to T:A transversion, which is one of the most common mutations found in human cancers.

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
