Direct repeats can cause mutation when
A) a person encounters a mutagen.
B) homologs misalign during meiosis such that the first copy of the gene on one chromosome lies opposite the second copy on the homolog.
C) introns are not removed promptly and their sequences are included in the gene product.
D) they bond within the same DNA strand, forming loops that disrupt replication enzymes.
E) they jump out of the chromosome and spontaneously invert.

Question

Quizplus · Accepted Answer

During meiosis, homologs misaligning can lead to unequal crossing over where the direct repeats may cause a deletion or duplication of genetic material which may lead to mutation. The other options are not related to the role of direct repeats in causing mutations.
