Which small nuclear ribonucleoproteins (snRNPs) are the primary components of the spliceosome?
Show answer and explanation
Correct answer: U1, U2, U4, U5, and U6
The spliceosome is assembled from five snRNPs: U1, U2, U4, U5, and U6. These snRNPs recognize the 5' splice site, branch point, and 3' splice site to coordinate the two transesterification reactions of pre-mRNA splicing.
