Final answer:

The genes that encode the proteins required for excision repair in E. coli bacteria are uvrA, uvrB, and uvrC.

Step-by-step explanation:

The genes that encode the proteins required for excision repair in E. coli bacteria are uvrA, uvrB, and uvrC.

The process of excision repair recognizes bulky changes in DNA, such as thymine dimers, and single-strand breaks. The specialized form of excision repair known as Transcription-Coupled Repair (TCR) prioritizes repairing genes that are actively being transcribed by deploying high-priority repair enzymes.
