True/false: Cut-and-paste mechanisms of a transposon can alter DNA causing a mutation.
True. The donor chromosome is identified through inverted repeat DNA sequences. The repeat sequences are brought together to form a loop and excised. The staggered breaks are repaired via DNA polymerase and DNA ligase. As a result, the insertion site is marked by short repeat sequences of the target DNA. Although the break from the donor chromosome is repaired, the process alters the DNA sequence, causing a mutation at the original site of the excised transposable element.
