What is the likely consequence of a mutation that alters the branch point within an intron?
A)no effect,since introns are not expressed
B)failure to form a lariat
C)failure of snRNPs to recognize the 5' end of intron
D)no exon shuffling
E)failure of snRNAs to combine with protein and form snRNPs

Question

Quizplus · Accepted Answer

The branch point within an intron is necessary for the formation of a lariat structure during splicing. Mutations that alter the branch point may cause splicing errors, leading to a failure to form a lariat and ultimately, aberrant mRNA processing.
