Verified step by step guidance

Understand the process of RNA splicing, which involves the removal of introns from a pre-mRNA transcript and the joining of exons.

Identify the key sequences required for splicing: the 5' GU sequence, the branch point, and the 3' AG sequence. These sequences are crucial for the recognition and removal of introns.

The 5' GU sequence is found at the beginning of the intron and is recognized by the spliceosome as the splice donor site.

The branch point is an adenine nucleotide located within the intron, typically near the 3' end, and is essential for the formation of the lariat structure during splicing.

The 3' AG sequence is located at the end of the intron and serves as the splice acceptor site. The term 'Splice Sequence' is not a specific sequence required for splicing, making it the correct answer to the question.
