Final answer:

After UvrD displaces the lesion-containing DNA section, the next step is nucleotide excision repair (NER), where the damaged DNA section is removed and replaced with new DNA using the remaining DNA strand as a template.

Step-by-step explanation:

After UvrD displaces the lesion-containing DNA section, the next step in the repair process is nucleotide excision repair (NER). In NER, the damaged DNA section is cut out by a group of proteins called exonucleases. The gap created by the excision is then filled in with new DNA using the remaining DNA strand as a template. This process restores the integrity of the DNA and prevents the mutation or malfunction of genes.
