Question

Match the following components of the spliceosome with their role in the splicing out of RNA introns. a. U1 b. U2 c. U4 d. U5 e. U6 H-bonds with U6 to form the catalytic center of the spliceosome. The first to bind the 5' splice site of the intron. Inhibits catalysis by the spliceosome until it dissociates from the complex. The first to bind the branchpoint of the intron.

2'OH 01 (the last five nucleotides of U2 snRNA) binds to the branchpoint of the intron. U2 snRNA forms H-bonds with U6 snRNA to form the catalytic center of the spliceosome. U1 snRNA is the first to bind the 5' splice site of the intron. U4 snRNA inhibits catalysis by the spliceosome until it dissociates from the complex. U6 snRNA is the first to bind the branchpoint of the intron.
