Hi Lisa, Please go check your PDB file. Are those bases written out like "DT" or "THY" or "Td". Coot recognizes certain format for DNA bases but I forgot which one coot likes. I don't have my laptop with me right now. My guess would be "Td". :)

I add DNA by "adding ideal DNA/RNA" in the other model. But I cannot edit chi angle of these nucletide, neither the mutate. When I press the mutate and my DNA, coot give amino acid not nucletide.
