The graph that follows shows the survival of four different E. coli strains after exposure to increasing doses of ultraviolet light. The wild-type strain is normal, but the other strains have a mutation in either a gene called uvrA, a gene called recA, or both. (b) What are the relative contributions of these genes to the repair of UV damage?

What aspect of DNA structure makes it possible for the proteins of nucleotide excision repair to recognize many different types of DNA damage? (c) the energy differences between correct and incorrect base pairs

What aspect of DNA structure makes it possible for the proteins of nucleotide excision repair to recognize many different types of DNA damage? (b) the antiparallel orientation of strands in the double helix

What aspect of DNA structure makes it possible for the proteins of nucleotide excision repair to recognize many different types of DNA damage? (a) the polarity of each DNA strand
