Question 16

Matching

Indicate whether the following statements are TRUE or FALSE.If a statement is false, explain why it is false.

Premises:

Responses:

The first step in repair requires a nuclease to remove a stretch of base pairs from the 5? end of each strand at the site of the break.

False

The 3? overhang "invades" the homologous DNA duplex, which can be used as a primer for the repair DNA polymerase.

True

The DNA template used to repair the broken strand is the homologous chromosome inherited from the other parent.

Homologous recombination cannot occur in prokaryotic cells, because they are haploid, and therefore have no extra copy of the chromosome to use as a template for repair.
