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

#Unit 11. Evolution and Behavior

Highest rates of substitutions in regions of the gene that have the least effect on function, such as the third position of a codon, flanking regions, and introns.

A surprising feature is the lack of conservation of sequence in MAR fragments. They are usually 70% A-T rich. cis-acting sites that regulate transcription are common, as are 5’ introns, and a recognition site for topoisomerase II is usually present in the MAR.
