Random dispersions are not common in nature, largely because abiotic conditions, resources, and interactions with other species are not randomly distributed

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

Plasminogen is converted to active plasmin when t-PA hydrolyzes the bond between Arg 560 and Val 561. plasmin also activated by urokinase-type plasminogen activator (u-PA).
