Splice sites are directional in nature. 5’ splice site -the left, or donor, site and the 3’ splice site - right, or acceptor, site. 

1. U2 addition to base pair with the branch site in the presence of ATP

2. U1 and U4 release Formation of the catalytic center in which U6 base pairs with the 5' splice site; U6 also base pairs with U2; U2 remains base paired with the branch site; U5 interacts with both exons through its loop.

So, 1 and 2 are the event of complex formation which are

A. Lariat formation is characterized by 2’-5’ phosphodiester bond

B. Lariat formation is characterized by 3’-5’ phosphodiester bond

C. Group II mitochondrial introns are excised by the same mechanism as nuclear pre-mRNAs via a lariat that is held together by a 2’–5’ bond.

D. Group II mitochondrial introns are excised by the different  mechanism as nuclear pre-mRNAs via a lariat that is held together by a 2’–5’ bond.
