Introns and transposons can act as sites where recombinational crossovers occur. Transposons can also catalyze genetic rearrangements. Rearrangements occurring within these sequences very detrimental than those occurring elsewhere in the genome.

A. True

B. False

False

Explanation:

Rearrangements on introns and transposons usually don't cause severe consequences because those sequences are not part of coding genes and therefore cannot code for proteins, and if a rearrangement occur within a coding sequence of a gene might cause an incomplete and non-functional protein causing severe consequences to expression levels of that particular gene.
