Question

Quizplus · Accepted Answer

Consensus sequences involved in splicing are located on introns bordering each splice site. These sequences provide specific signals for the spliceosome to identify and accurately remove introns from pre-mRNA transcripts. Consensus sequences include the 5' splice site (GU), the 3' splice site (AG), and the branch point site (A). These sites are recognized by specific RNA binding proteins that help recruit the spliceosome to the correct location on the pre-mRNA.
