During the processing of introns, a single snRNP complex catalyzes both the cleavage of the RNA and the joining of the cut ends. What would be the consequence if these two processes were catalyzed by separate enzymes not associated in a single complex?
1
The rate of RNA processing would be much faster.
2
The cell would be unable to identify the correct cleavage sites.
3
The exons might not be joined in the correct sequence.
4
Exons instead of introns would be cleaved from the RNA molecule.
