Question

Place the following steps of nucleotide excision repair in order. not all the choices will be used.

Answer 1

Nucleotide excision repair involves recognizing and removing damaged bases, and replacing them with correctly paired nucleotides.

Step-by-step explanation:

1. Nucleotide excision repair recognizes bulky, helix-distorting changes and single-strand breaks.
2. Enzymes make cuts on both the 3' and 5' ends of the damaged base, removing the segment of DNA.
3. The segment is replaced with correctly paired nucleotides by the action of DNA polymerase.
