IAA is synthesises by tryptophan and is primarily synthesized in a two-step process 

Indole-3-pyruvate (IPyA) as the intermediate. 

The second step in the pathway is carried out by the YUCCA gene product, a tryptophan aminotransferase.

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

Paul and Ann Ehrlich (1981) proposed an alternative called the rivet hypothesis Some species play a small but critical role in keeping the plane, the community, airborne, while other species do not
