What happens when nucleotide excision repair (NER) recognizes a damaged DNA segment with a lesion?
In bacteria, the UvrA protein aids NER in locating the damaged segment of DNA. How do the UvrA proteins carry out this function?
The molecular lesions that are formed by thymine or cytosine bases in DNA, caused by UV light, and repaired by nucleotide excision repair mechanisms are called _____________.
What is the primary function of the 3' to 5' exonuclease activity of DNA polymerase?
The DNA repair process involves the removal of the damaged sequence and the replacement of new sequences. Which of the following is involved in cleaving the DNA segments so that the damaged sequences will be removed?
