How would a large chromosomal inversion affect the expression of a gene if the gene is located between the two break points but no breaks occur within the gene?
A)The inversion would probably have no effect on gene expression.
B)The gene would not be transcribed because it would be oriented in the wrong direction.
C)The gene would be transcribed in the 3' to 5' direction.
D)The gene would be transcribed normally but the mRNA would be translated in the 3' to 5' direction.

If no breaks occur within the gene, its sequence and regulatory elements should remain intact, and the gene should be able to be transcribed and translated normally. The orientation of the gene would also remain the same, so it would still be transcribed in the 5' to 3' direction. Therefore, the large chromosomal inversion would probably have no effect on gene expression.
