Verified step by step guidance

Understand that pre-mRNA contains both exons and introns. Introns are non-coding regions that need to be removed to form mature mRNA.

Identify the introns in the given pre-mRNA sequence. In this problem, the underlined sections represent the introns.

Remove the introns from the pre-mRNA sequence. This involves deleting the underlined sections from the sequence.

Combine the remaining exons to form the mature mRNA sequence. Ensure that the sequence is continuous and correctly ordered.

Write down the sequence of the mature mRNA, which is the result after intron removal and exon splicing.
