A plant geneticist was examining the inversion mutation XI 501 in barley where a segment of DNA is removed, flipped, and reinserted in reverse order. The original protein functioned to assist in the separation of daughter cells during meiosis. A model of the initiation of normal protein translation is shown in the diagram. The action of the mutation is shown in orange. Using the model, which of the following predicts how the XI 501 mutation affects the protein produced? A - It creates a protein with the order of amino acids reversed, causing the protein to fold backward, reducing pollen functionality. B - It creates a nonsense protein that does not function in the cell, causing the cell to use energy to remove the proteins, reducing pollen fertility. C - It creates a protein that terminates at the mutation, causing the pollen to carry more than one copy of the genetic material in each granule. D - It creates a protein with half the amino acids correct and half reversed, reducing protein effectiveness and pollen viability.
