    A gene that was 5055 base pairs long resulted in the expression of functional proteins that were 350, 450 and 1500 amino acids long. What could be most likely reason for this?

    A) mRNA degradation

    B) Gene amplification

    C) Alternative splicing

    D) Mutations resulting in early termination signals

    Correct Answer: C

    Solution :

    Alternative RNA splicing is a form of regulation of gene expression where different mRNA molecules are produced from the same primary transcript, depending on this some RNA segments are treated as exons and some as introns. This enables the single gene of 5055 base pairs to code for more than one kind of polypeptide, depending on which segments are spliced together during RNA processing.
