Verified step by step guidance

Understand the role of Alu elements: Alu elements are short, repetitive sequences found throughout the human genome. They are a type of transposable element, meaning they can move around within the genome.

Learn about the AG splice site: The AG splice site is a critical part of the splicing process in eukaryotic cells. It is located at the 3' end of an intron and is necessary for the removal of introns from pre-mRNA during splicing.

Consider the impact of an Alu element insertion: If an Alu element inserts itself into the AG splice site, it can disrupt the normal splicing process. This is because the splice site sequence is altered, preventing the spliceosome from recognizing and properly removing the intron.

Predict the consequences for splicing: With the AG splice site disrupted, splicing would not occur correctly. This would lead to the retention of introns in the mRNA, potentially altering the reading frame or introducing premature stop codons.

Understand the effect on protein synthesis: The altered mRNA would likely result in a non-functional or truncated protein, as the normal sequence of amino acids would be disrupted. This is why the protein would be altered, as stated in the correct answer.
